Okay, another question that makes me feel kinda dumb.
How can I improve my N1's performance?
Specifically, how in the world do I get my nexus even close to the N1's I see on Linpack's "Top Devices"?
I'm running diet_2.6.33.2.hybrid_avs_925mv_OC with cyanogen 5.0.6. I can get 7.778 MFLOPS. Honestly, I don’t even know what that means. All I know is that I want more. Or do I? Does it even make that much of a difference in everyday usage?
I've noticed that in the JIT thread under development they talk about getting up to 17 MFLOPS, but no one really explains what JIT is or does. Just that it's unstable and that if your not sure what it is, you don't need it.
I can benchmarkPi in 2790 - how in the hell do I get it lower? Under the rom description of some of the top 50 they mention JIT and experimental kernels, but there's not much room for more than just the generic names of them. Where do I get these magical roms and kernels? Do I even want them? Are they so unstable that they can only be used to gain geek cred on some benchmark lists and once they hit the "high score" they explode in flames? Do I need safety goggles before I flash the update.zip?
Seriously though, I know I'm not the only one with these questions - so any info would help. And do me a favor, please do not respond to say that if I don't know - I don’t need to know. At one point, you didn't know either. No one was born with this knowledge.
I know there is a very bright person on here that is willing to take a couple of minutes to shed some light on us simpletons. I'd like to thank you in advance. Thanks.
Even if you get higher linpack scores, you will barely notice any difference in your devices performance... That's why I tend to ignore it. If its possible to get faster than Cyanogen ROMs (not in terms of linpack) I don't know how different things would be.. im curious about how quick Froyo is though.
Oh and have you searched, Jit has been covered in more places than just xda developers, several times it has been discussed I believe.. while using it, my Linpack scores did get into the double digits though - but this (not even that noticeable actually) speed increase was not worth the random reboots, and such. When Jit is stable though, it will be quite nice.. hopefully Froyo has it.
Linpack number did not make any differences in overall usage . Now, I am using my own UV kernel and setcpu max freq to 500MHz.. only... but, I still able to get 26.8 fps in Neocore's 3D benchmark. Playing games, 3D or not, still smooth and fluid.
I also waiting for Froyo and hope we can get even efficient and fast OS.
TQ.
I'm creating this thread based on what i read here: http://briefmobile.com/cyanogen-demonstrates-quadrants-flaws
I'd really like to know what lagfix gives me the best results and i lost my faith in quadrant. Are there any decent alternatives? Most benchmarks i know are only good for testing cpu performance...
Its not fair to say that quadrant sucks, and particularly I don't like that the article seems to be implying that the lagfixes that a lot of us are running are simply artificially inflating the SGS's score. The SGS has the best harware on the market crippled by bad firmware, and tbh I think its the lag fix that has allowed the hardware to be reflected in quadrant scores.
Anyway, quadrant doesn't suck. Its not perfect, but it does help you determine for example, how different ROMs on the same device compare for performance, as well as showing off things like GPUs that often don't get seen.
However it just runs a series of tests and weights the results accordingly. Particularly, the I/O seems to be given a lot of weight and so can be nobbled to increase the score. However, as anyone who has experienced excessive lag on their SGS can attest, it also works the other way. Without the lag fix, the SGS is a very pedestrian device, as the ~1000 quadrant scores tell you, while with the fix it FLIES.
Actually, some people are saying they notice no difference with the lag fixes it seems. And I've also seen forums full of people saying they can hear the difference between WASAPI/Exclusive audio and shared audio in Windows. Amazingly, out of the dozens of people trying to destroy me and demand it was implemented, none of them were willing to blind test (they were all just willing to say "it's obvious"). How many people here running the lagfix, have run any kind of blind test, or test with predictable steps to demonstrate a difference? Please, raise your hand people, because there is a huge difference between "it seems lag is gone" and "Lag is verified gone".
Quadrant is a guide, it doesn't test interactivity, and it only tests a few operations. It's similar to how a browser can pass ACID3, but have terrible compliance to new standards. Because people became so convinced of benchmarks accuracy, Nvidia and ATI started optimising for benchmarks.
Normal SSD's are also blazingly fast on benchmarks initially, but if they don't have TRIM, their performance drops significantly. That's another example of something benchmarks don't accurately test (because the testing is incomplete).
Use it to get a general idea of how the phone performs (although, specs might be more useful in some cases), but you probably need profiling and a predictable list of steps to diagnose the lag exactly. Run benchmarks which test according to the types of applications you are planning to run (if you play 3D games for instance, use a 3D game benchmark). But don't rely on them exclusively to tell you how well a device performs, because only running the applications and testing them yourselves can tell you.

But do you really think that one-click-lagix or whatever is that much faster than mimocan's one (like 2800 vs 1800)? I don't think so...

Predictable steps to demonstrate a difference:
1. Use 2 SGS, firmware of your choice
2. One with, say, 1 Click Lag Fix - the other one stock
3. Now for the test, perform simultaneously:
3.1. Open Market and go to "Downloads", update an app, close.
3.2. Open Contacts, quickly switch to favourites, dial Number. Drop call. Exit.
3.3. Open Messaging, conversation of your choice, quickly switch the writing language, write, send, exit.
3.4. bla bla goanforeva
Now if you don't notice an improvement there and in many other cases you most certainly have done something wrong.
If you are saying people are just being placebo-ed you are implying that everybody else besides you is unable to tell a real difference. Think about it, maybe it's the other way around.
When I got my device it came with the Asian JG4 firmware I think and I used it for 48hrs as a point of reference for this so called "lag" I updated my firmware to the latest we have and found zero difference in terms of performance ( same 2 day usage ) decided to flash my device with JM5 and used it w/o a lag fix for 2 days, notice a very slight improvment on how fast the inbox/contacts can open and then did a fresh flash with lagfix 2.x installed I didnt NOT notice any performance difference but I am always open and welcome to any lagfix that is stable,safe and fast ( in that order ) right now I have JG8 installed w/o lag fix and its very snappy, I still want to install a lag fix for this even if i dont see/feel any performance difference at all.. thats just me.. Now im wondering w/c lag fix is the most stable and safe.. stability/safty > speed
EDIT:
Also I believe it could be possible that certain versions of lagfixes work better with certain versions of firmware also, its all about getting the perfect combination.. altho my question still stands on w/c is the safest lagfix heheheh
Well actually i gave up on benchmarks.
To me the whole user experience is more important. If apps open instantly and the phone runs smooth then it's fine with me. I did notice some firmwares are better then other ones.
Right now i'm running JM1 (rev 3) with CFLagFix1.80 installed which makes the phone very stable and running smoothly so right now i'll stick to this firmware until a proper GPS fix is released or until Froyo is released.

Lol I think you didn't understand my question... I'm sure that these lag fixes all work, no doubt about that. But which of them is faster? For that i can't rely on quadrant i'm sure...
Today, a friend, called me to setup a new android phone for his wife. It was the cheap, very cheap, Alcatel Onetouch 908.
I transfered contacts, calendar events, configured emails and installed some apps from the market. The phone felt speedy, to be exact much more speedy than my Galaxy S and that started to bother me. What bothered me more was my friend, who has a Galaxy S II device. He told me out of the blue that alcatel felt speedier than his S II. I finished and 'take it for a walk'. I started sequently loading apps (browser, gmail, contants, market and talk) and then multitasked between them. The initial loading was almost immediate and, to my suprise, mutitasking was instant. My Galaxy felt like a second class device, my world shuttered... almost
I left my friend and I was angry, very angry. How could that be? I've tried numerous roms, customs and stock ones, with lagfixes enabled or disabled but, truth to be told, all of them felt like rubbish compared to an alcatel onet... I don't want to tell the evil's name!
Now, I am still angry but not with Alcatel,.. with Samsung! Am I wrong? What are your thoughts? Does anyone have an answer? Was just my imagination?
I don't suppose you have tried running 3D games on it?
knowledge is Power. Guard it well.
I did and it was fantastic... just kidding
No I didn't. But now you've said it, just for the laughs, next time I will be around, I'll try angry birds... if possible (although not a 3D game... I think)!
Ugliest thing ever seen on Internet
aaaaaaaaawwwwwwww, this is uglyyyyy, what an ugly phone, even if it had the speed of light, or even faster, the speed of thought or even much faster than those the speed of GOD, I would take the SGS anytime.
btw, try quadrant too, see if you get some noticable scores with it, if it's really worth your time, but if it was me, I wouldn't even set it up for a girl friend, let alone a friends girl.
well its the same story again u see a new android phone unused or if even used then used very very lightly(just calls,sms,have 10-25 apps. and all that) ! man any android pgone newly bought and used lightly can be very fast! i saw my friends galaxy ace on 2.2 bpught just 3 days ago and very lightly uaed and it was working like a lightning! if you want to see your phone this fast then flash stock jvs and you'll face lightning but as soon you get some apps in and start using it heavily youll start facing lags! download 100 apps. and do heavy multitasking on that alcatel for a week or so and youll start hating it and will throw it into a dustbin!

You should try CyanogenMod 7 (CM7) out of the box (no apps/games installed).
It's just fast - the speed is nearly amazing. Same thing with MIUI.
And just forget stock-ROMs. You won't want to use them after you have tried an AOSP-ROM (CM7 or MIUI).

Its not like that exactly but its very true both cm7 and minuit out of the box are amazing infraction I just installed 1.9.16 miui and it has just 7 apps. Installed and it's balzing fast ! But minuit has many problems of its own so I am moving back to Samsung based rom jetpack v5 spark very soon !

Thanks for the replies...
-I've tried CM7: it was fast but... it didn't felt home. So I dished it and went back to the samsung related rom's!
-Yes, SGS is prettier than 908 but really it's not so ugly. After all, my post was about speed, not beauty.
-So, if I load alcatel with 100+ apps I will feel the pain you say. We'll see... But if it's true then I will be angry again, very angry... with Google!
Memory Management
The thing about multitasking is that is related mainly with memory and memory management. I think it's true, if enough free memory exists any os will keep more tasks active and multitask between them will be instant...
But android keeps loading and unloading apps, in the background, which I almost never use but consume memory.
Skype is the perfect example. When i do not need it, I am signing off skype and go straight back to my home screen... Of course, as we all know, skype persists and never exits. It's just sits there consuming memory and doing nothing. If I try to kill it, android will happily and immediately reload it. The only way really kill it, is to uninstall it, but is this a solution?
One more example? The facebook app or the friencaster app. Even if I disable every automatic refresh or log off from facebook some part of them will keep running and like skype I cannot kill it.
The essence of all this is that: I own a phone with 512 mb of ram assisted with a powerful, 1 GHz, CPU, much - much more than an alcatel OT 908 and this doesn't show. Maybe is the 100+ apps I've installed in my phone, maybe is android, maybe is a bug, maybe it's me whining. Whatever is it... it's wrong and yes, I'm starting feeling angry, very angry with... Google and Samsung

Assuming your phone is rooted there are apps that can disable or prevent other apps from starting and running in the background- android optimize and autostarts seem to work for me.

Looking at the specs for the OneTouch, I am not surprised it is fast.
The 600mhz chip it is using is quite overpowered for what is effectively a featurephone. It is also supporting a much smaller, less advanced screen (256K colors, TFT) which frees up a LOT of cpu cycles for basic functions. This kind of speed while just being a phone is why feature phones aren't as dead as people keep assuming.
It is also running Froyo, which was made for this kind of phone and likely races on it, without having to worry about the sort of strains a Galaxy class smartphone puts on an OS.
Remember, if you install a slimmed down OS on a custom designed modern laptop, and ONLY install a handful of programs no doubt it will break speed records. However, to judge it against a fully loaded, professional install is like comparing apples and oranges.

alcatel ot 908 runs NFS shift, NOVA, Gangstar, BIA2, Sandstorm, Sims3, Rackless Racing, GuerillaBob, dead space....runs 99% hd games that don't requires armv7 or 2.3
it's way better then most off QVGA android and all msm7201 and msm7225.... (hvga and qvga)
for that money...
Well I have to say.
Just bought this second hand SGS to test and compare with my Desire HD.
If I can be honest. Both have the same clock freq and specs seems the same, but the DHD (lets call it that way) is alot faster than the SGS.
I am amazed how long it takes to just open the camera. On the DHD the camera app opens in half a second I think.
Then sometimes you click on something and nothing happens making you think that you didn't click anything at all. On the DHD opening anything is instant.
I'm running Darky 10.22 so if someone knows if I need to change something to make this a faster thing please let me know.
the only advantage of the desire hd and the alcatel ot 908 (i own one of these and a desire S, very similar to the hd hardware-wise) is that out-o-the-box, they're configured almost perfectly for their respective OS version and hardware.. Samsung makes some very tough and cutting-edge hardware, but they've always been lagging behind software-wise (and still are to some extent, i know what i'm talking about here too : my main device is a note2 N7100 and my dev/test device is my old -but almost unbreakable even when I'm the one who opens it up to solder or repair sthg in it- galaxy s2 i9100... None of those were left "stock", they're both fitted with CM10-derivated ROMs (most of the time a ParanoidAndroid or some derivate), heavily customized and "after-market" optimized (thanks to all the good tips&tweaks found here at XDA ^^) just to remedy those problems.. Never for my life would I leave one of these stock (I run a stock firmware on a dual-boot on the SGS2, but that's only for entering USSD codes, as these usually won't work on CM7/9/10 ROMs)... And yet, they're both way better when they're still "stock" than the Wave 1 was, with his powerful 1GHz Snapdragon CPU, but a puny 512Mb RAM -shared with the OS/CPU and GPU at that, leaving a mere 312Mb -give or take- to the poor user.. Far too low for its memory-hungry Bada OS,even in its latest and last 2.X versions.. I couldn't even open a second page in its Dolphin browser before it started shutting down background apps and closing widgets.. :s).

you won't be able to load that many apps on it m8... ^^
even with a big-ass 32Gb SD card, its /system and /data partitions are way too tiny for this number.. trust me, I've tried it, it choked at 20-30 tops for "average" apps (between 1 and 4Mb each)...
Ive noticed i have a small fleck of dust (which i find very very irritating). Anyone else got similar? Its most likely a dust flake between the digitizer and the screen as it moves relative to the image underneath. Sure it wasnt there when i bought it.
I've had mine since November and there is no dust under my screen unlike my iPhone 3G that I cleaned only a couple of months ago!
In the daylight i can see its a very white fleck under the digitiser. Very disappointed with this tab so far, slow, buggy and badly built. Such a shame as i love my Galaxy S2.

Half the stuff i've seen you moan about I do not have any issue with at all.
I would suggest you stick to your phone or just go buy an ipad as nothing will keep you satisfied.
No doubt you would have lot's to moan about with them as well.
My brother has 2 ipads and I still prefer my Tab 8.9 over them.
I'm running stock with Go Launcher and no problems here from my side. It runs as I would expect it too and it is an addition to my phone and pc, not a replacement of either.
Hate to say it, but choccy31 is right. You make 8.9 appear a lot worse than it is. It's not slow or buggy, with the latest CM9 ICS it's smooth enough and without problems. It's not badly built, you having dust under the screen does not mean we all have it. If you don't like it, you can always sell it, why keep it when everything is wrong with it?

Im sooo sorry i have upset you all, but the thing is rubbish. Its the worst Android device i have used by some way and ive used a lot. Im not the only one complaining about its speed it IS slow, fact there is no debate. Poor video that surprised me even knowing the Tegra limitations. Micro-stutter, lag, jerking. Maybe ill put up some comparison videos between the tab and the S2 and you will see what i mean. If it was cheap it wouldnt be so bad, but Sammy wanted £400 for this?? glad i didnt pay that.
I wont be getting an 'iPad' because its Apple and automatically fails, but i may well sell this on, swallow the loss and get something better. I should have gone with the Zoom, which is getting good support and is much smoother.
So go and sell it already. I dunno what Tab meets your requirements though, I guess the Transformer Prime is probably the closest you can get to the iPad in build and performance. Can't really think of any others that perform particularly better than this one, or that I can guarantee won't get dust (oh sh-------ttttt!!!!) under the screen.

Credibility = gone.
Why credibility gone? I hate the look of iOS which i think is very dull and I find Apple a horrible company. I buy Samsung to support free trade and as a protest to the way apple thinks it can limit choice by suing everyone over idiotic patents it should never have been granted.
The TF prime is better, but its not about raw power, its about optimization. There is no reason this tab needs to be so slow when the xoom isnt or even the Advent Vega!
Im going to wait for a real ICS ROM and see, by that time i may have got over the dust disappointment, but if it doesnt speed up its going.
You seem to think im asking to much for a tab to be able to actually function without stuttering, well i dont think i am. Im used to the slight Android stutter, but this is WAY beyond that. If i drag my finger slowly from screen to screen its smooth until it gets to about 40% of the way across, at which point it starts to stutter, however slowly i swipe. My S2 doesnt do that, even my Desire didnt, even my friends Wildfire doesnt and that has a 600mhz single core CPU.

Your Desire didn't? Hmm....as for being markedly worse than the Xoom with TW removed to make the OS more equivalent the performance is the same.
In any case it's hardly fair to compare the 8.9 to the S2 when the latter runs at a lower sub-HD resolution and isn't capable of displaying multiple large widgets. The 8.9 is quite up to HD video play back but then how is that worse than the S2?
I don't think anyone is saying that it's too much to ask for it to function without stuttering but it seems most, including myself, do not see the level of problems you appear to see. The example you give of stuttering at 40% swipe, I really don't see my home screens pause for fractions of a second as I swipe between them; it continues to move smoothly all the way in line with my finger movement.
Its smooth without widgets, but not with them. The more i use, the slower it gets. My S2 is running 6 full screen scrollable widgets, its has no slow down whatsoever. Sure WVGA makes life easier, but the Galaxy note is also smooth with ICS, that is HD and has the same CPU (in most markets). Tablet widgets are no bigger than phone ones., and even if they were the Tab struggles with the same ones my S2 has no issues with, even if they are smaller!
Ive given up using widgets now and it makes the device much nicer to use, but it seems like a waste of the larger screen.
For what its worth i have no issues with gaming.
The Note and S2 will both decode full rate 1080P blu-ray files, the tegra struggles with heavily reduced rate 720P. I have a copy of 'Drive' in 720P on my Laptop, S2 and Tab, the tab stutters and pauses, the others are smooth as silk.
You seem to be forgetting that the CPU and GPU in SGS 2 are more powerful than the Tegra 2 solution. Include also that more powerful device is running on a lower resolution screen, add the a lot more optimized ICS version for SGS 2, and you can clearly see the end result.
Is 8.9 perfectly smooth at this point? No, maybe it will never be, even with official ICS. I doubt we will see the improvement with buggy TouchWiz slapped on it, but at least devs will get some good stuff from it, like camera drivers and kernel. You can just hope for the best, or sell the tablet and purchase another more powerful model, something with Tegra 3 perhaps. We all know what's wrong with this model, we don't need someone to point it out.
High profile 720p and 1080p are just not doable on Tegra 2 solutions, it was like that from the start, there is nothing we can do to make it play nice without stuttering. I do get a decent framerate with DicePlayer on 1.4 GHz with some 720p movies, but not for long, on certain scenes it just becomes choppy. It's choppiest when you start the movie, but if you leave that tablet like that, and not swipe around, it gets better and better, only to be choppy again when more demanding scene comes up.
It is a shame, great screen going to waste, but if i sell it now, i don't know what tablet i would get to replace it. Transformer Prime is not cheap, i would need to add more money to get it, but i just love the form factor on this one. It's a difficult decision, and when the Tegra 3 tablets get their prices slashed, this thing will be even harder to sell.
Im not forgetting anything. My point is that if Tegra is so bad, it should never have been used in a top end device. I only paid £279 for mine, but if i paid the full £399 launch price i would be very upset.
The TF Prime still uses Tegra, the '3' isnt much better, as far as i can see its still broken, they are just throwing more broken cores at the problem in an attempt to fix it.
Its acceptable for now, but i still dont see why it should stutter with hardware acceleration enabled.

The Note and S2 will both decode full rate 1080P blu-ray files, the tegra struggles with heavily reduced rate 720P. I have a copy of 'Drive' in 720P on my Laptop, S2 and Tab, the tab stutters and pauses, the others are smooth as silk.

Widgets are the same size? 1 full screen widget on the 8.9 carries over twice as much information as 1 full screen widget on the S2.
How does Dual-core 1.4 GHz ARM Cortex-A9 in the Note equate to Dual-core 1GHz Cortex-A9 in the 8.9?
As for decoding, I would say that the almost double resolution on the 8.9 vs the S2 is a factor aside from CPU difference.
You say the Note is fine and is that from your own experience?

Because it means you aren't judging something objectively... Samsung have been attempting these crazy law suits too, and they did get their name in the smartphone/tablet market by being as close to Apple as possible... TouchWiz for Android 2 is basically Android hacked to look and act more like iOS and the phones up until S2 were all designed to look like iPhone alternatives (look how the Galaxy S is the iPhone 3GS and then the Galaxy Ace is the iPhone 4...), and the people who design the devices and the legal departments are completely unrelated, it's not like each company is some dude who makes every decision.

or even the Advent Vega!

I had an Advent Vega... Doesn't even begin to compare to this thing... Was fun for modding but to actually use it was a POS... I mean come on, if you're into modding you can put an unfinished homebrew HoneyComb/ICS on it which doesn't support the camera (lol, the nasty VGA thing) or if not you can run the ridiculous stock ROM with inch-thick navigation bar... The accelerometer doesn't even work right. I think I can put up with choppy homescreen transitions...
You seem to think im asking to much for a tab to be able to actually function without stuttering, well i dont think i am.

Not at all, we just can't understand why you don't rid yourself of it and get something else if it makes you so mad. We want you to be happy with whatever device you get but at the same time we don't want to be shouted about at how crappy stuff that we like supposedly is.
Im used to the slight Android stutter, but this is WAY beyond that. If i drag my finger slowly from screen to screen its smooth until it gets to about 40% of the way across, at which point it starts to stutter, however slowly i swipe.
Click to expand...

Ah yes, I know what you mean. The homescreens move with my finger but they do lose framerate. Never been important to me as homescreens are, erm, they're just to get you into the apps, and you only swipe between them when you want to see your other widgets/icons, it's not like a frequent thing. I find it stutters a LOT worse when using some live wallpapers, make sure you don't use one of them. A lot of the Honeycomb devices I've used do this though. There aren't many I've seen to run the homescreens smoothly without modding. I mean, for me, it's one of the best Android tablets I've used, the form factor, performance (for the size & weight), screen, etc. all come together really nicely. It's only the homescreen that doesn't seem smooth for me...
Have you tried overclocking? I've heard that can fix the issue. I read somewhere that the homescreens don't use hardware acceleration on this tab.
It's HoneyComb's silly 3D screens thing, the way swiping between them has that unnecessary 3D effect, I mean seriously, what is the practical use of that, it uses way more resources and also affects the intuitiveness of using a touch screen (when you keep things "flat", it creates the feeling of sliding something under your fingers, when the 3D comes in it separates it and feels more like minority report 'gestures'), it seems to be pointless showing off and causes a lot of the stuttering on Android tabs.
Also, have you considered giving the Galaxy Tab 10.1 a try? I've read that it runs better and is more compatible. For me no tabs compare to the Samsung ones in design, weight, etc., the performance isn't perfect but it's the kind of sacrifice you make to get something impossibly thin and light.
My S2 doesnt do that, even my Desire didnt, even my friends Wildfire doesnt and that has a 600mhz single core CPU.

Yeah but these are all Android 2 devices which run at 800x480...
I never claimed to be objective, i despise Apple, and im very happy to say why. The galaxys look like an evolution of older Sammy phones and the Tabs look like large versions of them. They didnt copy Apple, call it 'convergent evolution' if you must. Apple are being patent trolls, they started it, the others need to finish it.
I love the look of the 8.9, its lovely, i just want the excessive stutter gone. homescreens are important to Android, its not just about the apps.
I know the Vega is rubbish, but it still manages to be smoother than the Tab.. Thats really sad.
Lower res phones should be smoother yes, but the Galaxy Note is smoother as well, that has the same res. The Xoom is smoother, in fact the 8.9 is the worst T2 powered tab ive used. What i want is ICS with Apex launcher than is smooth and jitter free. A pause or 2 i can handle, but not the gritty jerky laggy mess it currently is. It makes it feel so cheap and low end.
As for the dust, i used a statically charged plastic rod, and managed to make the fleck 'jump' off screen, behind the bezel i guess. It may return but its gone or now.

Well, it's not even worth getting into here, but it's still just a company, no need to take it personally, they all do these same things and our tablets wouldn't exist if iPad didn't, and wouldn't be half as great if they weren't competing with it.

Well, only if you mod the crap out of it, and I'm sure you can mod this tab to run better if you overclock it and use the right ROMs and stuff...

Good idea! If it comes back you can just do it again. Great thinking though.
Android has widgets, iOS doesnt. iOS's interface is just a basic list of apps. Android has so much more, yes widgets are apps in a sense i suppose, but they are interactive. If their performance is very poor it ruins the experience. Most apps perform ok in themselves, but the homescreen is the face of the device and it must be smooth.
Yes the Vega must be modded to be smooth, but i standby what i said. A Stock Vega is better than a stock 8.9, and ive done everything i can to make this smooth (ROMs, kernels, overclocks, tweaks), its still slower than a modded Vega.
The Note has ICS now and it destroys the 8.9 with ICS builds. The 8.9 feels like a 500mhz single core unit next to a Note. The Note running GB previously doesnt explain why its faster, it should mean its slower!
The Xoom might be heavier but it has no 'performance enhancing' extras that the 8.9 doesnt have, in fact the 8.9 has faster RAM, or at least a better implemented memory subsystem. Its still manages to be slower.
I simply dont accept the answer 'Blame Honeycomb'. If ICS fixes the issues then i believe Samsung must have changed something else, some limitation or previous decision that was hindering the unit.
Tegra2 for whatever reason is a horrible CPU. I've used a few omap4 tablets and they just seem way smoother than tegra2. I mean a tegra 3 is finally smooth but nvidias cpus seem to be "on paper" good but real world bad each generation. Seem like they come out first with a spec set but poorly implemented once competitors are out. I mean the snapdragon s4 quad will probably destroy tegra 3
The S4 duals beat the T3!
I knew Tegra was old and slow, but i did think that maybe Samsung would have made the best of the bad CPU, it seems they have made the worst of it.
Hello
I have upgraded my Tab S7 to Tab S8. And I have expected new device be much faster and smoother, but what I found that games are really lagging! It was perfectly smooth on S7 but not on S8. Game mode does not help much. I do not play a log of games on this tablet as I used it mostly for developement, but I do play Harry Potter Puzzle and Spells and this game lags pretty bad on S8.
What can be done to fix it or should I wait for Samsung to release update? I do know about Samsung's throttling on S8 devices but I never expect it to be that bad.
And in addition (don't want to open another thread) it seems that S8 has more aggressive memory settings because it unloads apps from memory over time. Which never happened on S7. S8 has more memory and I think it should keep more opened apps, not reloading them. And yes, settings in developer section (do not keep activities) is not enabled

This has to do to android 12, s7 was only on android 11, but also is on 12 now. So then it automatically puts apps into deep sleep. You can remove that under battery settings area and remove apps from deep sleep mode.
About lagging it might be new game mode from samsung since apparently samsung did on purpose limit hardware but added a settings into app that let's you gain more performance in games. Should be in game engine or w.e name is and then settings and then Labs and enable experimental feature there that should boost performance and stop limit the hardware for game.
When I replaces S7 it was already on Android 12 but I never observed such behavior. Anyway, I have put game into never sleep list. As about lags, unfortunately I found no options for that

I was noticing this particular with emulation since I don't play many native android games. When playing Sonic Colors at native res on my Tab S7+, it would almost never go below 30fps in level, and almost never below 60fps in the hub and menus. However, when I tried doing the same on the S8+, I had a bunch of stuttering and performance issues no matter what version of dolphin I used. There was a workaround to this (at least for me). These issues only happened when I restored my data to my new S8+ with Smart Switch, but when I just put all my data and stuff on there manually, the issues seemingly stopped happening. The only game I throttle in is Fortnite, which didn't have the 90fps option even though the S7+ did. The game still didn't feel much different before and after the throttle, still pretty consistent framerates overall.
Edit: Just fixing typos.

Did you used cloud backup or restored through cable or it's the same thing? I have similar problem, but with benchmark results. My device can't get even average model score in 3DMark (about 2 to 8%). Geekbench scores are worse than snapdragon 865 devices. I don't know what's going on. I already tried to reflash stock rom with odin, but that didn't help. Hopefully not using cloud backup will help.

I initially restored with a cable, but once I started getting shawty performance, I made a backup on my sd card and restored it from there with Smart Switch. I never used cloud backup since that takes a lot of time for me. After getting suboptimal results with both, I just bit the bullet and slowly started adding everything and getting it to how it was on my old devices. Only then did I get getting substatiall better results. Now I can run a lot of Wii/GC/3DS/PS2 games at 1.5x, 2x, and sometimes even 3x without getting throttled. Not sure why using smart switch tanked my performance, but all I know is that it's not tanking now.
Thats interesting. Because I also moved data using cable. I do not know how good is cloud since I never did it before (only on Apple devices).
I might try to fully format tablet and test it again.
Will provide more information later

I tried formatting few days ago, and that didn't help. At least for me this problem is not related to Smart Switch. Do you also have bad benchmark scores? I understand that benchmarks are not very good indicator of performance (especially due to GOS), but I expect to have at least average SD8gen1 performance, not the level of SD855.
Did reset to factory settings. It is much better at least for now. Benchmark - tested only Geekbench 5. Result the same
Hi.. I'm experiencing the same problem here.. any updates regarding this problem? My geekbench score can't even surpass an exynos 2100.. it only achieve around 700ish on single core.. the first time I notice this is when I tried playing granturismo with aethersx2.. and it can't even handle the 1x reso.. hhhh.. really frustrated here.. please kindly share any clues regarding this topic thanks in advance.. sorry not a native English speaker
I had same problem, but, i solved using this:
ADB AppControl 1.7.5
(disable all game service (i'm not remember how many)). For me it's work great
--edit
i disabled bixdy and others apps too
First.. thank you for the answer! Might try it out later..
So it's like disabling the "GOS" right? Is it different from the "alternate game performance" option in game booster? They said it's the "official" way to disable the GOS.. but yeah I didn't find any difference after enabling that option though... Hmm..
Hmm...also.. What makes me wonder is.. I saw some reviewers review this device without any tweaking needed and they could achieve a 8gen1'ish results in benchmarks.. and also if you know ETA prime on YouTube.. he reviewed a tab s8 ultra and is able to run a granturismo 4 with aethersx2 (ps2 emulator) in 3x reso in default settings with no problems... I know it's a different device but it's supposed to have a same Chip right?
All of this things makes me frustrated because it was not what i expected from a 8gen1 device.. moreover I saw a sd870 device could run the granturismo 4 in the same settings with no problems.. it really broke my heart..
The issue mainly lies in the SOC.
Even though, SD8 Gen 1 has a much higher peak performance, especially in GPU, it can't sustain that performance due to excesive power consumption which results in thermal throttling.
GOS is another thing that affects the whole experience, it's limiting the performance of the device.

Yeah.. I think this is mainly what cause the problem.. The 8gen1 itself..
a quick update regarding this from me..
I've done some re-test in benchmark and real game perfomance but this time im doing it in a well conditioned (cooled) room..
previously I was doing the test and gaming and in a room without any Air Conditioner and I lived in a tropical country which is really hot and humid...
the benchmark results (3d wildlife) came out Nice in a well cooled room, It scores what most of Tab S8 would score and the real life perfomance (PS2 emulator) is also improved..
it manages to handle GranTurismo 4 in aethersx2 with 3x reso on safe setting quite well..
the CPU temperature is well managed in around 35'ish Celcius compared to 45'ish when not using any air conditioner...

CPU temperature 35 Celsius degrees? Are you talking about an ABSOLUTE idle? Because even if you would put a bag of ice on the TAB it wouldn't sit that low under usage. Even small loads will put the CPU around 50-60 Celsius degrees. Under heavy load up to 85-90 till the thermal throttle hits in.
Also, that ONE wildlife mark test doesn't do much. The idea is stability, better known as SUSTAINED performance, and that's where SD8 Gen 1 ****s itself. Try running a Wildlife standard stress test (20-minute loop) and post the screenshot, you'll see what I mean.

I only saw the perf-z indicator from samsung though.. so yeah.. i know i might just straight up wrong about this I just straight saying what I saw.. and honestly I'm not an expert in this.. just a mere consumer..
Yeah I got you.. it goes downhill even after the first one.. what I'm trying to say was that I never reach that score before in warm room so yeah it's mainly the CPU problem..
What mainly being my concern before was I'm scared that I got scammed with a fake/unoriginal/refurbished tab s8.....
Harry Potter plays fluently on Tab S8 Plus here.
I have sent my S8 to my mom and bought S8 plus. Did not restore, set it up from scratch. No lagging in games, including HP. So, it could be related to thermal soliton in S8 plus as it is bigger

Yes you have to run 4 adb Commands that also disables game booster and game launcher then GOS will stay disabled even after restart. I've done this and turn ram plus off. I also disabled or put into deep sleep all of the bs apps. I also went to advance features and turned off all of everything causes I don't use the s-pen so no need for air actions and stuff to be on. If you want the ADB commands let me know.
