Hi, so after cm rooting i noticed there is also an ext4 upgrade...is this worth it and will I have data lose during the change? Im on 2.3.3 and am wondering if it is really worth it! Ed
are you kidding me?
besides that this post should not even be in this forum (try Q & A) there are hundreds of other posts and threads discussing this topic if you only use your -(0-0)- !
Yes and no
It may have some advantages but as for what I'm not sure but as for nay major advantages I would say no. I'm still using EXT2 and my benchmarkes are still 1900+. I've tried almost all the other lagfixes and found no real advantage. The only thing I hate about custom kernels with lagfix is the secondary samsung splash screens and custom splash screen. They kill the post time.
I would say it isn't as worth it as what people say. First thing most people do after converting their filesystem is run quadrant. It's possible that improved quadrant scores don't translate to real world performance though.
Even worse, running quadrant actually engages the placebo effect so you walk in with a more positive impression. Meanwhile, I don't recall ever seeing anyone from the EXT4/EXT2 i9000 community running blind tests, and neither development community has actually shown any evidence formal testing has been performed. All the arguments seem to be based around quadrant and PC testing. If methods like this were applied to clinical testing, every drug would pass
Honestly, give both a try, but do it blindly.
Why Quadrant may be wrong
This is just a bit of background why Quadrant's scores may not reflect real life performance. Until we check the actual ratio's of Quadrant, and compare with actual usage ratio's though, we can't identify how "real" it's scores are.
Consider a benchmark which produces 1 final score. It may be calculated by:
[MAX TIME - Time to read 1000mb] + [Max time - time to write 1000MB]. In this case, both scores contribute to 50% of the final score, which can be worth 2x MAX Time.
Scenario 1: Time to read/write is both the same
Scenario 2: Read time is 1% shorter than Scenario 1, but write time is 1% longer. Both will have the same score in Quadrant..
Scenario 3: Read time is 5% longer than Scenario 1, but write time is 50% shorter. Scenario 3 will get the best score
Which one is ACTUALLY faster though. The benchmark-toting individuals will claim Scenario 3 is faster, because of the score. HOWEVER, that may be incorrect. Consider the following:
If a user reads 100x more data than they write:
1) Clearly, faster read scores are more important.
2) The BEST filesystem will be Scenario 2, despite being equal last.
3) Scenario 1 will be mid place
4) The scenario with the best score, will actually have the WORST performance.
5) A drop in 1% read performance would need a HUGE increase in write performance to actually be faster.
Until we have an idea of how accurate Quadrant REALLY is, run your own tests, and do so without knowing which filesystem is running. High quadrant scores may boost your e-penis size, but as you can see, it is theoretically possible for the scores which are produced to score slower performing filesystems more highly than faster ones. Disappointingly though, a decreasing number of users/developers at XDA these days are actually interested in the truth, and simply in not being wrong.
Even worse, the community for some reason seems VERY anti-RFS, and wont give it a chance regardless. It might be a LOT better than it used to be. Either way, it seems to be good enough for me.
Ignore the theatrics and run a blind test. That's the only way to determine what is ACTUALLY faster.

I guess you mean CF root right? Will just answer the data loose question. No you shouldnt. But do a backup before. Its fast and easy (if you are on CF root that is)
If its worth depends on you? You experience any lag on rfs? Phone slow?

@ramrod54 , where did you get ext2 support on JVK? And what the?
What samsung splash screens and custom splash? What rom and kernel are you on? And what lagfixes? And we both know quadrant score doesnt matter does it ?
Yes, it's worth it. Some things (Android Market, Gmail) works really MUCH faster then on rfs.

Hrm, I've never noticed a difference. Market is slow on any room, hell market.android.com is slow too. Gmail always worked fast for me, on any rom.
Personally, I don't see or feel the point in using anything but rfs, but I suppose if someone has half a bazillion apps installed, then maybe an alternative filesystem might be better.
I say try it. If you notice a difference, good for you. If you don't, then stick with rfs.
What about battery performance ? from what I have read, battery performance is also better with RFS.
I always use ex4, its not as needed now on gingerbread but I just prefer the file system...it is better than RFS...but RFS has improved a great deal so you may not noticed that much difference, the rom may become a little smoother..You wont get data lose because of ex4, maybe the way the kernel is built...dont forget that 2.3.3 gingerbread is still beta and without the source code for the kernel you cant expect great things yet, although chainfire has done some amazing work and now we can change the file system using his app....works really well.
Also regarding battery, the difference in performance is such a small margin that its not even an issue.
What alot of people aren't aware of is that the Nexus S for example uses ex4 file system as default straight out of the box
Its not just a lagfix for the galaxy s, its a very good file system too...
Just a side note on Quadrant, ex4, ex2 will trick the app...if you buy the pro version, you will see how much the file system stretches on the bar...Quadrant is more for fun....or HTC
Think it´s worth cause rfs slow down your system after a while
Hi.
Anyone tried to improve performance like on the SGS in changeing filesystem?
Also is the hw acceleration possible, adding a line in the biuld.prop file to enable gpu in scrolling etc?
I must say that my lg p500 on cyanogen7 is much snappier, and milestone can be choppy sometimes. I feel also that qualcomm processors have better performance in the system than milestone's TI. Omap.
I know that p500 has more ram, but I feel like someting is wrong in the milestone that slows down a bit. I know that hvga is more than 2x less pixels than wvga, but still, maybe some hacks will help. Lagfix and HW acceleration helps on many android phones from lg, samsung etc.
HW acceleration is enabled by default.
My Milestone is actually very smooooooooooooth..... and snappy!
Yes, unbearable without SuperCharging it, but effing awesome with SuperCharging

Interesting What ROM did you use? and What overclock frequency?
At the moment CM7 at 1100mhz.
But come to think of it, I don't think I need 1100mhz anymore lol
I'm often "underclocking" it to 800mhz without really noticing too much difference.
But the main thing is, any ROM would fly with supercharging
Go on, ask him wat supercharging is!

Did you see that CM7 final release is out for Milestone? He said he tweaked the memory a bit.
ya I looked.
It looks alot like my v5 gscript in that he put the launcher in it's own spot with priority 2 and same kill threshold.
I put it in the second slot but he put it in the 3rd slot.
He also pushed the big chunk of apps (secondary server) down the list to the 5th slot from the 4th whereas I had moved them up from the 4th to the 3rd.
But he increased the memory limit so that chunk of apps actually start getting killed at 24 mb!
Previously, those apps weren't getting killed until ram got down to 16mb so it's actually a very big change.
So by default, it may actually behave like my Balanced 1 v5 gscript. heh.
The difference is the Heavy Weight App. We both have it in the 4th slot but in CM7 Heavy Weight App is more protected and has more priority than secondary server (the big chunk of apps) whereas I have secondary servers as being more important.
I want to see what apps fall in that heavy weight category before my update
Will the fact that apps get killed at 24MB now instead of 16MB affect the way that you can now bulletproof two apps in this recent update? Because he warns that it is RAM intensive, but what does it do to the apps in the other slots?
It just means if you're bulletproofing an app, another app that you're not paying attention to will get killed instead of the one you want to keep running. But it would bounce back anyway and something else would get killed.
They just play musical chairs and take turns updating once in awhile.
btw, I adjusted the minfree on my phone and gave heavy weight it's own slot but there is no apps in that spot at all
I run stuff and let it sit and keep refreshing but I never see a heavyweight.

You are right! What on earth is SuperCharging???
I googled throug XDA and i cant find a clear meaning of SuperCharging
Yea, supercharge tweaks are great. So maybe changeing the filesystem? Some people said that it wont do any boost, but maybe its worth trying.
I disabled dsi bug workaround and phone is flying on adw ex. I definitely need supercharge script as phone lags sometimes in different apps after some time.
And swap would be nice on our stones, but nobody knows how to do it by kernel module.
Try the super test script on page 38 of my thread.
My next update will be based on that with different minfree values

Hi
Everybody talk about changing the VM heap value, but... what is the difference after changing it? What about increase its value? And decrease it?
On the CM7 thread adamz667 post this: http://forum.xda-developers.com/showpost.php?p=15065093&postcount=4569
Anyone can confirm that?
Thanks
Increasing cm heap means that apps can use more memory which makes them run faster but then since tbey use up more mem u will have less free memory.
Sent from my Milestone using XDA App
Here you got some definition:
VM Heap Size
The heap is an area of dynamic memory allocated to programs. With a larger heap size, there is more memory for the program and the garbage collector can run more efficiently. Therefore, it is possible to get better performance by setting a larger VM heap size.
However, if you set it too high, you can run out of free memory which can trigger swapping which will degrade performance. Therefore the VM setting is a trade-off.
The optimal value will depend on the RAM on the device as well as the programs and usage patterns, therefore the optimal setting can often only be determined by the user experimentally.
Default value: varies between devices

I have tested all of them today and the best results was with 16mb.
How I was testing it?
Shadow Guardian HD is a very heavy game for MM's ram memory. So I've tested every vm heap size on one and the same level of SGHD, with the same run environment and game was most playable on 16mb (no freezes, reboots, no returns to home screen).
Really 16mb. Which rom? And how far did you get in the game?

I am using CM7rc10 (14.06.2011) I am now in 4th episode (level?) - Medusa Sanctuary.
That is very very interesting. I'm gonna have to give cm7 another chance. Maybe rc10 is a lot better than rc4 (last cm7 I tried)
Sent from my Milestone using XDA App
i also have good performance with 16m tried most settings from extremely large to extremely small...
also png optimized most apps again and again... (which decreased the size of the apps by almost 10mb again - quite sure that it does not make much of a difference)
don't have any app locked in memory and only one homescreen with adw ex without widgets...
dunno till now i have not experienced any issues with lost sms or phone calls...
but i'm aware of that it could happen with my settings so it needs more testing, jit turned off etc. phone works like a charm since i switched from froyomod a week ago or so.

Are you sure u tried 16 mb. Because I just tried shadow guardian on cm7 rc10 with ur settings and zepplinrox supercharger on balance and tbh it was rather language at times

I've tried jit off and VM heat on 16MB but not get any result.
The launcher was freezing 3 or 4 times, and all games get a minimal improve: 3 seconds more until FC.
I'm testing with: Asphalt 6 and Brothers In Arms 2 (Gameloft games) and Age of Wind v2.2. All versions for MM, with people that play them on stock rom.

well as i said i do not use that memory intensive apps.
(i think my biggest apps are maps and the browser, and the browser barely goes beyond 30mb, so 2 vm's with 16mb, instead of 2 with 24. but most apps stay below 10mb so i think for my use it is a good solution)
also i debloated the rom massively and replaced most system apps with smaller ones.
cm7 performs very well with this settings, at least for me. (no redraws, no lags in ui no freezes etc...)
like i said i don't use games on my stone
edit: only genie news & weather app reloads often but i think it simply has a high priority.

That is quite interesting. On ho no I
And 20mb with balanced 3 supercharger works great. But not so well on 16mb

I had tried 16mb weeks ago when somebody suggested it.
That lasted about 5 minutes.
Scrolling between adw screens was brutally choppy.
Swipe finger, wait, look at watch, then bam - the screen suddenly decides to quickly jump to the next screen...

I've got the same with 12mb vm heap. But when I use 16mb everything works fine on CM7 and HO!NO! CM7. Maybe it depends on rom/apps you use and your own configuration.
I guess.
But I'm used to fast, smooth and lots of free ram no matter what rom I'm using

yeah 12mb is to small... experienced some errors with it too.
i have to say that for me everyhing between 16 and 32 mb seems to do not do much of a difference, but with 32mb my system uses some more RAM right after boot.
after a while it usally uses less (around 80-90mb sometimes less, sometimes more) so i normally have around 60mb free RAM, which seems to be enough.
i'm out of this discussion for now, but i have to say that i rly think ur VM Heap settings should match the apps u use.
so just try different settings.
@Zeppe
yay never experienced that, but i use only one Homescreen anyway. and ADWEX is rly memory friendly : )

Anyone used this app? Some users reported to have significant lag reduction when starting apps but in my case my O2X was already snappy so the difference is not night and day with this app running but it might have improved a little.

I tried it and it should be working, but I don't seem to see any dramatic improvement.
Sure, there is a bit of improvement but it might be subtle or just placebo.

Saw RC's comment about it before even knowing it existed, still tried it and might have experienced a very small difference which I still don't kown if it's just placebo or some part of the script which somehow speed things up a little.
This following discussion is pretty interesting though:

I tried and I can see some difference, opening times are different, not instant opening, but better. Placebo? Placebo effect is documented to function... Anyway, still discussion goes ahead, and something new still comes out.

i was thinking about it, so i changed minimum frequency to 1000mhz instead of 216 or 312 mhz. It's definitely snappier when i unlock the phone and start using it. but switching between apps, is still faster w/ seeder on.
I owned a T705, it was my phone and tablet, i loved it.
However, the camera was bad, and the whole Interface was very jittery.
I understand that this device is not getting updates from Samsung, but man, i sure miss the screen real state, also beautiful.
Have lollipop custom roms reached a state where they improve over samsungs touchwiz performance?
I am considering it, alas i read that a new Tab S might be coming.
Thanks.
We have unofficial build of cm12 and its very stable. Way better than touchwiz too. Its still being worked on so its not perfect. CM11 is great on it also. Both do improve performance over touchwiz. There is also a new tab s coming soon but that always expected from samsung. Up to you

How is the battery life of the cm12?
This is what I got. I measured screen on times and standby times and this is what i got. This is from the T800 so you may get less because of lte and other stuff
Well, one of the problems if you own a T-705 is that under CM you will lose the phone features (CM 11 and 12 are for the T-700 only). I suggest that you try IronRom instead: definitely smoother than stock.
One rumor we heard is that the next generation flagship tablet will have a 4:3 screen ratio and a 64-bit processor, but it won't be coming until the end of year or late summer at the least. My preference is to have a 16:10 screen on my tab s.
I'd like a 4:3 personally since I do way more reading on my tablet than anything else. 16:10 is better for watching videos, but that's what I have my TV for
I don't have the money to upgrade so soon though
Thank you all for your Input.
My question is, with say, IronRom, is the performance improvement noticeable?
I found The Tab S beautiful, but very choppy overall, maybe the processor wasnt optimized for 2k, even with some custom ROMs (i used Selamba mostly back in the day) the performance of the UI was very below par, however, applications ran well enough, this led me to believe that it might have been touchwiz and not the hardware itself.
Thank you.

The part where its choppy on stock firmware is just scrolling through the launcher. It lags when just scrolling through the launcher and switching between some apps (ex clash of clans). Iron rom has none of that. Sometimes the GUI lags when you have too many apps open and it uses all the ram. Example like 16 games open all at once. It can freeze and force a reboot. GUI doesnt lag that much like the launcher. Hope this helps!

I am not sure which part of scrolling through launcher is supposed to give lag. I have three screens worth of application icons in the app launcher and I had no problems with those. As for having 16 games open, I don't see how that represents typical usage.

Lol yeah. If your a typical user, 4-6 apps open or less, it can handle it. 16 apps open would be a user who stresses the cpu and gpu.
Well, in my experience there is some lag basically everywhere with the stock ROM, not only in the launcher. Loading pages and scrolling is also slightly choppy in any browser, and also in applications that use WebView components.
I wouldn't rate this as very evident, especially because the CPU has plenty of cores, but it is there.
With IronRom + SkyHigh kernel + Nova Launcher + things get smoothened just that small bit that makes everything feel right
