Increase pagepool?

In some of the other forums, i've noticed that some of the devices, especially the older ones, have some ridiculously large pagepool sizes.
If I understand correctly, the larger your pagepool is, the faster (relatively) you phone will go?
Now that we have some ridiculously memory-filled roms, i think we should look into investing in some increased pagepool. My question is how i would go about in increasing my pagepool to 12mb or potentially 14mb or even 16mb?

that is reducing your ram. you will only have 10 mb free and there is no performance erasing...
it was tested on wizard roms. 12mb as default pagepool is not nessescary.
4mb will give you a lot of free memory and less performance...
6mb is the right way to go...

ah i see. i was using 4mb for pagepool. I'll change it to 6mb

[Q] Amount of RAM?

I thought in read in the specs before buying this phone that it had 512 MB of RAM.
When I check in my task manager it says I only have 326 MB of RAM total..
Don't tell me we (Canadians) have less ram than everyone else??

it is not just the Canada version
all SGS phones have 512 of RAM but only 326 available for end users the rest are used by the phone services

Isn't it a 2.1 thing?
Sent from my GT-I9000 using Tapatalk

The kernel supports up to 326MB RAM. Newer versions support full 512MB.
I guess when Froyo is out officially we will have full 512MB support.

Its sounds to me this phone was made for frayo and 2.1 is just each what they had to go with the Iphone 4 would have gotten alot of sgs customers If the galaxy didn't release when it did

phandroid.com has a couple of shots of a Leaked Samsung Fascinate Equipment Guide . The second photo is quite interesting, it says
Onboard memory : 512MB Flash/384MB RAM
What does that mean ?? We have 384MB of RAM after all ??

That's another phone.. Doesn't mean much.
Our official news/press release said we have 512MB, so we have 512MB. Don't get too worried. Samsung may have decided simply to put the RAM to better use for now (to speed up other areas). Apparently, the epic uses a RAM disk to speed things up, so it's possible ours has a 160MB Ramdisk too

I am relatively new to android, but from what I have read on the internet Fascinate is simply another Galaxy S variant customized to Verizon, just like Captivate, Vibrant and Epic 4G, isnt it ?? Why would they mess around with the core components just for one carrier ?

I would like to believe that too , My only concern is Gingerbread compatibility. I know even if we have 512MB Gingerbread is not guaranteed. But 384MB means a definite no go , right ??

They added a flash for one... It might be to save money for the carrier. But, this variant uses EVDO which I believe is US only, and its possible they need more space on the circuit board too, for other features they add. Either way, our phone is advertised as 512MB.

Nobody knows. In the rumour world, there is a crapload of BS. Don't believe anything you hear unless Google says it directly (and publicly). Remember, Kevin Rose told us he SAW the iPhone before it was released, and it had multiple batteries. And that guy constantly says rumors (the only ones I see him ever get right are obvious ones or ones which have proof already if you know where to look). If rumors by idiots like him consume the the internet in hours, its easy for anyone else to do the same.
To the best of my knowledge, Google has never stated the RAM required.. That being said, the epic 4g apparently uses a 160GB RAMdisk to speed it up. It's possible our phone does the same (which explains the memory gap). But I have seen nobody prove or disprove whether we have 512MB of RAM which can be accessed by the OS. All I know is that Samsung have stated we do and haven't retracted it..

The photo is in line with previous speculation that the galaxy s has 384mb ddr(?) ram and 128mb onedram(fast ram dedicated to graphics??) / onenand(not actually ram??? 0_0) .. its all a bit confusing.

EDIT2: at first I was a little concerned, but after reading the other topics, I'm fairly reassured that the "ram issue" isn't really a bit issue at all, once compared to nexus one, desire etc.

SEMC seems to run a Sony Ericsson blog. And his post is mainly guesses, as with the others. Nobody has actually proven anything. However, the arguments against 512MB of ram are that 128MB is flash, and that Samsung don't know the difference between RAM and flash (which doesn't make too much sense, as they clearly differentiate between the two elsewhere).
Until proven otherwise, there is no reason to believe that we don't have 512MB of physical RAM.

I checked it as well, the Desire has 576 mb but it shows only 400 mb,
my old X10 has 384 but only shows 270 mb, it might be the kernel, but Ive read on a unreliable website that the rest was dedicated to the GPU just like a shared videocard on a Laptop...

Yeah, it's likely some is dedicated towards GPU and such, and it's likely to be OneDRAM. But, there doesn't seem to be any definitive proof..

iam sure its the kernel guys.. my old desire after flash mod kernel can get full 512mb and free memory up to 300mb using advanced task manager..

What does this mean for us? Possible that we only have 384 megs of ram?

and this is a dev issue how? it belongs in the Q&A section.

Since a lot of people here are trying to figure out how to free up ram up to the 512 limit ( or even close to it) it could belong here.

This has been discussed at length how much ram ourphones have. Posting a picture of a vzw ad does not helped dev's do anything with freeing up our ram.

Hmm, just checked gsmarena and there is nothing on the ram of the fascinate, so this might just be true. O.O On gsmarena, it shows as all the other galaxy s phones with 512 mb of ram.
if it is, that kinda sucks, even though you get camera flash, i would gladly take the extra 130mb~ or so of ram :/

Can I just make a quick point here without stepping on anyone's feet?
When you buy a computer advertised to have 4gb of ram, do you actually get to use all 4gb of that ram? No. Your computer takes some of it and divides it up for other purposes. Some is strictly for the OS, some goes and get dedicated to your GPU, and the rest you get to use. The story is the same for our phones. There is a 512mb chip in there for ram. You will only get to use ~380mb of it.
Same for a hard drive. As I've said once before...

That is cuz how microsoft's file system, NTFS, which counts 1024 kb = 1 mb. That is why it is off. This has nothing to do with NTFS. This is most likely that the ram isnt there. If what you said is the case, that would mean all of the galaxy s phones would be advertised as 304 mb, cuz that is all the is usable at stock.
And your hard drive comparison, thats because for 1 TB to show up in windows, it would have to be 1024 GB instead of the normal 1000 GB just because NTFS has a different way of counting bytes.

No, that is a really terrible analogy. You buy a 1TB hard drive. You get 1TB, counted in decimal. Just because you don't comprehend the difference between binary and decimal doesn't mean you're suddenly losing space. IT IS THE SAME AMOUNT OF SPACE.
Pretend I point to a can of paint and say it is navy blue. Some other guy comes along and says it is actually 000080 in RGB Hex value. You return your can of pain to the store and yell at the manager that you didn't get navy blue.
That's pretty much what you're saying about hard drives. You are not losing anything at all. Period. End of discussion. A computer simply interprets bits in a different numbering system than what we are used to (binary vs. decimal). There is no magic. There is no loss.
Likewise, your 4GB of RAM analogy is also incredibly flawed. When I buy 4GB of RAM, do I get 4GB? Yes, absolutely. There is exactly 4096KB of RAM there. I can have it sitting on my desk and there is 4GB there. I can install it in my machine and there is 4GB there. What it is used for is irrelevant. It is still 4GB that I paid for. I know that for a fact.
For our phones, we do not know for sure that there is exactly 512MB of RAM and, even if we did, we do not know if there is exactly 208MB of RAM being used for system processes or dedicated to the GPU. It could just be reserved for absolutely no purpose or it could not exist at all (after all, 208MB of RAM is an absurdly large amount of RAM to use for the system when we're still using EVEN MORE for android processes we can clearly see in any decent task manager). You don't know and neither do I.

It has nothing to do with the NTFS file system. It has to do with how the OS counts (megabyte vs mebibyte - base 10 vs base 2).
In regards to RAM, PC manufacturers do state if the GPU is using shared memory. Other than a non-discrete GPU, RAM in a computer isn't typically statically reserved.
The Galaxy S has never had 384~ MB available to the user. The most that can be squeezed out at present, and still have a fully functional phone, is 340~ MB.

So perhaps a developer has more to say about this... since they DEVELOP? It is awful lot of RAM to be used for unknown stuff

Eh, he still has a point. There's 512 there, just some of it is used for the system. I forgive Samsung for this since all android phones (heck, all OS's) suffer this phenomena.
I read somewhere that Samsung chose to statically allocate it rather than dynamically, just to really increase stability. So the cappy may be worse but still you always see this in some form

You just said the RAM was different.
Anyways, that doesn't change my point that some RAM is always taken by the system OS. Android is a little unique in that each hardware distributor is allowed to tweak the OS so the level of system RAM reserved changes but its still there always

They said the amount of *AVAILABLE* RAM shows differently. Insinuating that when two pieces of hardware that are identical show different amounts of available RAM (available, not physically present) that there is something else going on that we the user aren't aware of.
Unknowns like this lead to people asking questions. People asking questions lead to answers. Answers lead to optimizations by brilliant XDA developers. Brilliant XDA developers making optimizations lead to terribly happy users like myself.
So it's in the interest of everyone posting in these forums to ask questions and try to come up with possible answers besides "No".
Yes, we know OSes use RAM and allocates it to various things. I think the issue as stated by others already is that we don't know how MUCH RAM is being used by the OS in our case.
If one device says we have 340 MB RAM available, and another almost identical device says 444 MB RAM available then that means it's POSSIBLE that our brilliant XDA developers could discover how to free up another 100 MB RAM to do fascinating things with.
It's NOT possible for them to discover that if people asking questions and helpful suggestions are shut down by negative people simply stating "NO".

https://github.com/cmsgs/android_device_samsung_galaxys/blob/master/config
you can go here and check out the reserved memory allocation. See line 766 and 1394 under "reserved memory config." the reserved mem adds up to approx. 140 mb. give or take a few. That would put us pretty close to 512. Some of that can be freed up as has been done on the i9000 forum. They have successfully freed up 40-50 mb to be used as free ram, although freeing up too much from certain locations can have negative results such as hindering 720p playback. See speedmod froyo in the i9000 forum for details. [KERNEL] SpeedMod Froyo 340MB RAM Optimized + Sharpness fix by Hardcore. I also think sztupy, developer of z4mod (I believe) had something to do with it.
Just a matter of time and hopefully we will have the same.

I know they're both advertised as having 512MB, but the Tab has more physical RAM than the phone. You can find a post somewhere in the forum talking about the memory chip configuration. The Tab has 128MB more than the phone. That's the primary reason the Tab has so much more available memory.

I just had to chime in - to satisfy the MS/HDD argument, an even better analogy: You purchase a Dell computer that is advertised to have a 500gb HDD. It arrives at your door only for you to find that (GASP!) the Windows install took 10gb, leaving you with only 490gb.
I believe that most if not all mobile handset manufacturers do this to some extemt. My Droid Incredible had 16gb of onboard storage advertised. They didn't mention that 4gb of that was reserved for the actual Android OS. It honestly never crossed my mind to feel swindled - it's just how it is.
That being said, I grow tired of this thread popping up as bumped when I check the Dev Forums for updates. While this discussion certainly has merit, it's nothing new to developers, nor does it have merit for them in particular.
Mods, can we get this thread locked or moved?

Post Your Smartbench Scores!

With so many ROMS to choose from, I thought that it would be nice to have people post their Smartbench scores along with pertinent information such as ROM used, VM Heap Size, etc.
I like Smartbench much more than Quadrant since it breaks up the result in 2 categories and are more reliable - since Quadrant scores are all over the map depending on the direction of the wind in Tokyo, Japan
I think that with alot of input, we can more easily determine which ROMS are truly faster or maybe help people figure out if there is a misconfiguration on their phone.
I figure scores in between 800-900 (Productivity) and 1100-1200 (Games) range would be pretty good - since I had got below 700 and 1100 before tweaking.
Anyway, here is my best score so far:

ROM..................................: CM 612 0.07-11.01.28
VM Heap Size......................: 48 mb
[email protected]: 1100mhz @ 64 vsel
Memory Management (in AOR): Mild - Keep Launcher Alive
Governor............................: Performance
Battery Level......................: 100%

Here's mine at 900Mhz-56vsel using Moto APAC / Interactive Governer / VM size 28mb

I forgot to mention that your honeycomb theme goes fast for me

Wouldn't be more relevant if we all use the same settings (CPU speed , vm , governor) , just to see the performance differences between the ROMs?

Sure, comparing apples to apples makes sense.
Most people seem to be in the 900 to 1000 mhz range so they can still be comparable.
Say a phone at 900mhz scores higher or the same as a phone at 1000mhz, then it could be that the phone at 900mhz is running a much faster rom.
It would be nice if people would start posting scores from different roms indeed.
I'll be trying a different rom soon so I would post the score with the same settings that I used in the first post.

Rom: shadowmod b3
CPU: 1000mhz @ 60vsel
governor: smartass
BTW, what are meant by productivity index and game index respectively ???

Wow nice games index score...
I would imagine that Productivity Index is the cpu efficiency/performance and the Games index would the related to the Graphics performance ie. higher frames per second = smoother game play.
Maybe you can try increasing your VM heap size to 40 or 48 mb and reboot to see if it increases your Productivity score.

I have googled the term and some said it is the Max memory that is allowed for a single app to use.
And most set their vm head size at 16 MB.
Is there any bad effect if I set it at a greater value??
Sent from my A853 using XDA App

I thought that the default value in CM6 was 24mb.
I saw your post via tapatalk so I actually tested it out at 64mb and the phone was incredibly quick and smooth.
I can't say that it affected benchmark scores much but I was surprised at how quickly Smartbench loaded up!
If you look at the OP, in the status bar I have an icon with 2 vertical yellow bars.
That's SeePU.
The first bar is CPU load/activity and the second bar is free memory.
When I was doing the test with that large VM heap size, that second bar was near the top and green - meaning lots of free ram. I guess the memory got flushed out. No need for a task killer lol.
Then I closed smartbench and there was no desktop lag and process monitor was showing over 60mb of free ram despite the fact that my memory management setting in AOR is set to mild.
I did not see any ill effects at all but keep in mind that my dalvik cache is on an ext2 partition so that may be a factor as well.
This thread that I just found pretty interesting. http://forum.cyanogenmod.com/topic/2692-vm-heap-size/
Also, as far as I can figure, an app will only use all the VM Heap memory if it needs it.
If it needs 40 mb and the vm heap is only 16 mb, that app's performance will be crap when compared to how it would perform if the VM heap was 40 or 48mb.
I guess the only downside would be that there is the potential for background apps (media player, etc...) to close because the foreground app is using up too much memory. If that's the case then I'd lower the VM heap to a more balanced level.
The lowest I'm going is my usual 48mb but I'm gonna stick with 64mb for awhile...
Edit: Hey it actually helped with linpack... I managed 15 MFLOPS

Yeah I said near the top that it didn't effect the benchmark scores much - meaning smartbench.
But it did give me consistent high scores in linpack and I even got over 15 mflops which has never happened to me before.
I saw the post that you are referring to and they actually talk about it in that cyanogenmod forum thread that I linked. A couple of people explain VM heap very well and pretty much explain why that 12mb test didn't mean anything.
The main thing is that my phone is actually running alot smoother with a larger VM heap though

I have raised the size to 48mb
and it seems to be better
What is the Max vm head size that I can set??

I had it at 64 mb for a couple of days but I think that it is just too big in that when I checked running processes, some apps or services that I want to be running would not be running... so I put it back to 48mb

[Q] Question To The Developers About The RAM

When I look at the XSP device info, the ram size 766 mb even though the phone is 1 gb
compared with another 1 gb ram phone, in the device info it says 971 mb, so that results in about 200 mb free extra memory in the second phone
I searched a lot and couldn't find anything about this.
Is there a way to make the Xperia SP show 900+ mb?
before anyone says that its system reserved, how come the second phone has a much smaller reserved value?
---------------------------------------------------------------------------------------------------------------------------------------------------------------
Second phone is Tengda T94 (chinese phone) the multitasking difference in the XSP cannot be compared to the T94, the T94 is so much better
its very frustrating to look around for a solution for a 1 gb ram phone! to get better multitasking!!! i feel like im looking for a solution for an entry android device. i love this phone i wish i can find a way to get better multitasking as its an important basic smartphone feature

I think its just bad ram management. My SP on CM10.2 works without problems
Shows about 841 mb (total)
Sony Software can't do this!

It is something to do with the kernel I think
Sent from my C5303 using XDA Premium 4 mobile app

there is nothing u could do in stock ROM unless u greenify everything + remove every bloatwares
but theres nothing wrong with the running ram, just let it filled... android is different alot than PC, in android the RAM is used to be filled, its normal... i remember some XDA members said that "unused ram is a wasted ram"
MAYBE, sony intented to do that to limit the apps prosessing

im not a developer and i dont understand why the 2 phones i mentioned both 1 gb ram and 1 show quarter missing , can anyone at least explain to us why does such a thing exist, ive been looking everywhere online but i couldnt find an answer! is it really that hard to answer?
is there a solution to make the sp show 900+ mb in system info in antutu benchmark

well i found the answer, this 250 mb of ram that is hidden is reserved for the gpu as i read on some article.
and there could be a way to amend that a little bit through some kernel.
im now disappointed and thinking about replacing this phone as multitasking is very poor and its a basic feature of a smart phone.
its strange to see a chinese phone that is 110 usd faster with better multitasking and even the screen quality and gaming is better! why cant a top company like sony do something to give access to the 1 gb ram which is very needed for basic use

don't think more Ram will get you faster, new chips it is ..( bigger Cpu Cache, bigger GPU, Dual channel memory )
sony need those 200mb for gpu, because it's a multimedia hd phone and gaming phone ( 320 gpu like xz :fingers-crossed: )...so you get hd movie recorder , hd games, even you can trow this to hd tv ...
i have this $200 chinnese quadcore with msm8225 , 203 gpu,1Gb ram ... and i believe xsp faster than this chinnese quadcore
and this phone don't have NFC, can't play full hd movie, lags on hd games, can't record full hd movie, no os update, and the list will go on ...
antutu about 13k on this chip, on quadcore mediatek chip about 16k, xsp about 21k ... you tell me who is the fastest ...
so, don't bother what is show on bench, user experience is...:laugh:

Please no more chinese phone jokes,
unless you found one with a Snapdragon 600/800 etc, the GPU performance is in those 110 USD chinese "Super phones" is very poor.
Not even comparable to the Adreno 225 let alone 320.

Haha,my friend has a sgs4 and that has 2gb ram and 1.81 user accesible.At times his phone has 700-900 mb free...so dont complain

Phone is very good.And i honestly believe that another 100-150 MB of ram wouldnt make any difference...They would in my previous xperia X8 which had 27MB free ram all the time...But when you have 350+ free as i do now, being 500 wont change a thing.
With 250 EUR i got a phone with almost the performance of xpZ (yeah cause of 720 screen but its ok for me ) that wont slow down on everything you throw at it.So dont complain about the little missing RAM which as said is not wasted but is being used but for the GPU.:good:
