Let's get this whole "page pool" sorted. - JAMin, XDA Neo, S200 ROM Development

Can anyone tell me how the size of the page pool affects
1. Stability
2. Speed
3. Available memory after a soft reset.
With my limited info, I believe it to be the case that with a *higher* page pool, you get more OS stability, more speed, but less available memory for other apps to run. Would that be correct?

it depends
some ppl like Big PP
some ppl do not

Huh? I'm not asking what people like. I just want to know what effect a larger or a smaller page pool has on those 3 things. So, no one knows?

Well i am back at WM5 now. Made a 2MB pagepool rom.
Stable
Fast
Free memory after boot : 36MB

cand you do that on touchv3?
Or you can give us a guide how to do it??

So, you claim that a very low p.p. will increase both stability and speed? Why do we have larger p.p.'s then?

no,large page pool,more speed,small page pool ... guess what ) and dude,wm5 sux...

Please explain why WM5 sux

in my opinion a big page pool is not really faster.
ok, some apps start faster but the free ram is too low.
with lots of free program memory you can keep running all your important apps and you don't have to close and start them every time.
so with always opened apps your daily usage of your ppc should be much more fluider than with a big page pool and only 1x mb free program memory.
i hope i could explain it with my sucking english

You do make a point, but most people prefer to close their apps all the time.
Its like with windows desktops, some people have 50 windows open in their taskbar and some only 2 or 3.
If you are one of the people that like opened apps your right, I like fresh app starts so I prefer a nice 8mb pool size

Tweaks to Improve Speed

I was following monytoo's suggestions (http://wiki.xda-developers.com/index.php?pagename=Windows_Mobile_6_Standard) in the hope to reduce the amount of processes being loaded at startup.
However, no success; nothing changes. Is there anything else that can be done?
Thx in advance

HTC S740
WM 6.1
Rose has 100 MB+ free RAM, there is no need to perform these dangerous tweaks to save few kB.
Not what my system shows (I have - yet - no SD)
In any case - what could be dangerous? The machine runs as well with or without these services taken off. It actually seems to ignore the registry in this case ...
Free RAM has nothing to do with store memory. There is 150+ MB of RAM and 100+ MB for storage.
Be careful, there is one tweak that disables receiving SMS so I recommend you restoring the original settings.
Point well taken; I indeed mixed up the 2 for a moment (the system shows 130MB of free memory)
As to SMS - no problem there. It works perfectly.
Now that we agree on the availability of RAM - any thoughts on speed (e.g.: the device takes about 35 sec to boot - is this alright?). In my desktop configuration (W2K) I reduced boot time by almost 30% when I cut down on the launch of services. Here, the deletion of services according to your earlier post brings no effect whatever.
W2K Pro for a PC and Windows mobile 6.1 Standard for smarthone just cannot be compared. The Rose is a great device and provided you haven't totally screwed it up by installin a lot of junk (in which was perform a factory reset) leave it alone - trust me it's performance is good. 35s boot is normal (you should not compare this to your Nokia phone from 8 years ago - not a good comparaison
Just enjoy - this is one WM device that doesn't need much tinkering.

That may well be true. Yet - it still is Microsoft. And if I know one thing about them - having had the singular misfortune of being exposed to their "misdeeds" for more than 20 years - it is that Mr Gates has not come to this world to make things easier for the rest of us. Therefore, tinkering, as you like to call it, almost always is a necessity

256Mb Ram .. but so little to play with?

It puzzles me that my TG01 boasts a healthy sounding 256MB of RAM, but often all that is available when all apps are terminated is no more than 80MB free. Having a look at the background processes, these seem to account for about 40MB which would suggest there should be about 200MB free at worst! What is all the "spare" memory preoccupied with? Is there a utility that will give a breakdown of how the RAM is allocated?
Why is this a problem? Because, more often than not, I get an error using Internet Explorer that there isn't quite enough memory to run Adobe Flash.
dont use IE lol ... IE memory managment is one of the things they fixed in 6.5.3 ... when i had 4 tabs open in opera and had 35mb free , i started to panic too , but then i opened 14 tabs and i still had 20mb+ free , so its all good , its quite dynamic

Ram Problem
yeah i agree with you! on the htc touch hd, it had 288 mb of ram, and after a clean soft reset and touchflo 3d running, it had 199mb of ram left.
on our TG01 it has 256mb ram, an after i installed touchflo 3d 2.5, i have 58mb of ram after soft reset. there Is so little to use.
This makes no sense
There has to be something we are missing. how do we free up more of this memory? What is it being saved for that we cannot even seeit?
Guys wait for clean roms.
I am sure our chefts will cook us some awesome roms soon.
BTW I am anew proud owner of TG01 (no voice calling quality problem.)
Currently with rogers canada
even with the ability of flashing clean roms, there still seems to be big problemss with ram. perhaps toshiba sold their devices with false specs?
its fine aslong as u avoid the sense roms
and be sure to softreset every few days

Nope. It has 818MB of RAM that you can actually use. I usually have about 450MB of RAM left at after booting up, so go ahead and get it. It's got 306MB of RAM more than any other phone on the market.
Oh, and BTW, I'm pretty sure there are some people working on a way to free up all of the RAM in the Atrix. Search the thread in development and I'm sure you'll find some posts about it all somewhere...
Beyond the dual core, the RAM is the next best reason for me for this phone. I start up near 500 and can run anything I want and it never skips a beat.
I use the System Info Widget to track things and I have never dropped below 215 with a ton of crap running!

Haha yea and all my other crazy ass apps that come up on startup! Weather, set cpu, battery minder ECT. And I take that back, i usually have 500 to 520 a couple minutes after startup. I had 450 at the time...but on my Bravo I usually have only about 150MB of RAM after startup it has 512 like all the other phones. Id say it's average for an average phone to take 400MB of RAM for the Android System plus all of your other apps that start up. Oh, and BTW, Blur isn't helping, and I hate you can't end any of that S**T.

1GB RAM ???

hello all,
sorry if this has been asked before (it prolly has been, i didnt find it though):
the atrix got 1gb ram right? after a reboot there is only around 570mb free ram...
after a few days without rebooting iam stuck around 440-480mb ram...
1st: where is my 1gb?
2nd: why do i even loose more ram?
sorry iam really new to android.
thanks for the help.

Yes it has 1gb 200mb is reserved for the webtop and 800mb is for android
you might want to read up on how linux and android USE ram also. free ram is wasted ram
is it bloatware
So its normal i only have roughly 600 mb left. Ok thx a lot.
Can you help me with another problem.?
I read somewhere that you don't need a task killer. I have always used one to get back to like 500mb. Now you tell me unused ram is wasted ram. I installed autokiller after some advice and opened some games and stuff. Later i was at 154 unused ram. After 2 hours standby i was at 237mb unused ram. Would i ever get back to 400+ ? And is it really better or at least soesnt matter for battery life?
Thx for help

I found that to be true (not needing a task killer) but only under Gingerbread (I've noticed that since I upgraded my Nexus One to Gingerbread), but on FroYo that's not really the case, or so I've noitced.
However I found that the task killer included on the Atrix works really well (much better than any other on the Market). It's just a matter of selecting the apps that you don't want to auto close and that's it. The battery last a bit longer and the device does not heat up at all.
Cheers!

Heres how I see it.
On your computer, you're always scrambling for more ram right? Because you are running multiple applications at once. You have a music player, a game, chat, windows itself, antivirus etc.
On your phone, it depends more on your processor speed. You arent multitasking like crazy (and if you are your phone would start to heat up really rapidly) Android allocates ram accordingly to what you are running in the foreground and apps that arent open but were opened recently. That way, if you reopen a recently closed app, it is still in memory and will open quicker. If you don't access the closed app after a while, it will clear itself from memory. You definitely don't need a task killer for android, only more processing speed.

Doubt regarding ram

I don't seem to understand that why do the sIII has too less free ram, it doesn't have HTC sense either, but so what's the problem
Comparison on normal basis:
Free Ram on:
-HTC explorer = 240
-SIII = 340
-Optimus one = 330
Q1
Can someone tell me what app or the list of useless apps that are ram hungry?
Q2
Why do all devices have less ram example, Optimus one has 512 mb ram and available 421 with cm9
S3 has 1Gb and available around 760
Why, and if it is system reserved then why do we see system apps in taskillers

'free' shows 778MB after conversion from KB to MB (1MB = 1024KB)
That 1GB includes hardware-reserved locations suche as for the GPU which, unlike mid- to high-end desktop computers has no real dedicated memory. Additionally there are the camera app (especially video encoding is notoriously high on RAM due to the codec specifications), the modem, ...
I'm also not sure if that 1GB is, as hardware manufacturers often tend to do, 1'000'000'000 Byte (1 GB according to hardware manufacturer'sIEC definition) or 1073741824 Byte (as defined by SI and adopted by software manufacturers)
That would reduce the capacity by a further 7.37% on RAW storage.

You shouldn't be using Task Killers. I still remember them being a de-facto requirement in Eclair, but since Froyo they are obsolete and cause more harm than they can do good.
(At least in theory, memory management only recently with ICS got reliable and performant enough to completely get rid of them)

Get houmiak Task Manager from Market and look for yourself. Many useful features are completely unnecessary for most of us, so you can freeze them to gain memory. (Don't uninstall since you can defrost frozen apps instantly if you ever needed it)
Those included for me the Exchange service, Allshare, ... . There's a whole list of apps which are safe to remove.
(Note that 'safe to remove' does not mean you won't need it: that depends on what you actually use)

"Free" memory is a very interesting defition. What do you call 'free' memory?
If an app is closed, should Android immediatly remove it from Cache? You'll probably say yes to increase free memory.
However there are multiple reasons why it's not done
- free memory is wasted memory. If the phone doesn't use it, what's the point of having it?
- it doesn't cost anything in terms of CPU-cycles to "remove" cached apps from RAM whenever the space is needed [*]
- Should you multitask back in the app, it's immediatly available. Depending on the app, even with everything exactly as you left it
[*] Well it does, but not more than immediatly removing it when the app is closed.
If you work a lot within the same app, chances are that your free memory is far below 1MB since it keeps everything in Cache if it should ever be needed. By exiting or killing an app that value increases since some data is always freed. But that does not mean the phone will magically get faster. If you still don't believe me; what if I told you that there is NO major operating system (Mac OsX, Windows NT, iOS, Linux, BSD, ...) that does not cache. You just don't see the raw values Linux shows on most of them, but faked values where the cache is substracted.
If you want details, I recommend reading about Paging ("Swap") and In-Memory Caching on Wikipedia. They have some excellent articles.

My phone never lags. Sometimes there is a brief delay when a screen redraws upon app change. I hardly think the phone becomes a "waste" at this point. If you want to see what lag really feels like go get a second hand HTC desire.

It is sad that the available ram is less than on the S2 to be honest.
I'm running with 80-200mb free all the time, even been down to around 50mb when using the phone, the S2 I was never under 150mb.
But then again, the S3 is faster than the S2

wow, you lucky s3 fellow, i have been experiencing ram issues, when I say that, know that I have considered the fact that more RAM used the better - more apps in memory, improves app switching/launching speed(all that philosophical BS which people give with pride, when someone posts a query on RAM. My RAM exceeds 700 MB and goes up to 796 MB with less than 50 MB at times; and this is with 10-15 trusted lightweight apps installed, This was prevalent since the stock firmware ICS and even is present after the JB update. More RAM used is good only when it doesn't affect performance, and doesn't force apps to struggling to stay in memory, causing them to frequently restart.
though i found a partial fix, which gave a lil speed boost -> http://forum.xda-developers.com/showthread.php?t=1787263&highlight=ram+problem
This helped me a lil(Disabling ripple effect in lockscreen), though to totally resolve the issue, i might have to go for a custom rom/kernel or hope for sammy boys to release an update soon -> http://forum.xda-developers.com/showthread.php?t=1926380&page=3
