Where's my RAM? - JASJAR, XDA Exec, MDA Pro General

http://blogs.msdn.com/windowsmobile/archive/2005/11/17/494177.aspx
an MS-dev explanation of where the chunks of your Universal-RAM had gone

Still doesn't make sense that the OS occupies more than twice as much space in RAM after a soft reset. They make it sound like previous editions of Windows Mobile didn't have to do the same things. Typical MS bloatware IMO. :roll:

++++ We are solving Universal's memory leak problem... ++++

Bigface title to a not sure method, but with hoping success for the object.
I think everybody is fighting with this nerve-racking memory bug in wm5+vga+universal thing.
Me too.
Very very hard.
I'm very angry with this statement.
I bought the newest, most professional PDA with the oldest, most amateur speed.
It is not new for anybody, I'm sure.
I've opened this topic to solve this *******, because I think ROMupgrade is coming very slow.
I tried hundreds of different things to keep my RAM's free memory and get my Jasjar/MDApro/Exec more speed.
I'd like to share my experience to you and I'd like you to share your experience to us, to understand why does it happen.
OK....so.....
1) My first and biggest remark in this theme:
gwes.exe (this is a system process, which is runnig continously with the system to let us using functions of our device)
It is runnig with the following modules: (on my device, it is not sure all on yours too, but I think almost)
lrgwesex.dll
touch.dll
commctrl.dll.0409.mui
commctrl.dll
aygshell.dll
keybddr.dll
ddi.dll
toolhelp.dll
gwes.exe.0409.mui
toolhelp.dll
ceddk.dll
coredll.dll.0409.mui
ossvcs.dll
ole32.dll
coredll.dll
So...this gwes.exe starts with the system after a soft reset taking about 6MB RAM memory.
If you are watching carefully, when your RAM is getting less this gwes.exe is getting bigger.
In one of my examples after a soft reset I had 24MB free memory, and when I had just something like 4MB I checked the running services.
And you know what???
gwes.exe was using by then 19.5MB from the memory!!!!!!!!!!!
So I think when you start an application, system files are using more memory with applications, but when you close the application you have just more with the memory using by this application but less with the memory using by the system with this application.
I'm not sure with this, but i'm sure there is a big problem with this gwes.exe service.
I found more processes (device.exe, filesys.exe, cprog.exe, shell32.exe, repllog.exe) which are doing something the same but not that much than gwes.exe.
So if somebody has some reflections about this write it down to us!
2) A lot of people say there is a hack in the registry / storage manager cache keys which we increase, system will operate with higher speed.
I'm not sure now.
I tried a lot with different keys, and my suggestion is totally the opposite than that: when I set different cache keys (glyphcache, storage cahes...) to zero the system eats less memory and something the same with the speed.
Interesting.
I don't have exact results in these points, but thinking about somewhere here the answers.
Please help us to find the solution together to solve this irritating bug!

I'm searching for the answers countinously too...
I never have a memory issue with my dopod900, even after a week of usage with various games and application, the memory still remain around 22++M. Will try to check up the result and post it here.
I also want to know why........
After the reset, my machine has around 20M left and after a while, only 11M left and that's last for quite a long time. I have no experience that the memory is only around 4M....

Are you using the stock machine without all the tweaks ? I mean have you applied optimizations like cache settings, etc ?
I'm just wondering if it might have something to do with some of the changes we made to improve performance :?
The issue is partially duie to Microsoft, but also partially due to 3rd party developers. I know for a fact that a lot of developers do not bother to have their applications issue defragment or compact instructions to the operating system after closing. They take up place and resources in the memory heap but do not "give them back" after they close.
You can blame the Universal as much as you want, but in my opinion it's one hell of a machine that had the misfortune to be the first officially released WM5 machine out there. Microsoft is indeed working on speed, stability and other issues form their end (the latest O2 Exec rom is by far the fastest and most stable ROM there is), but the developers need to do their bit as well and start working on their program's behaviour.

Hmmm, you would think that Microsoft would be smart enough to put in some checks to automatically release the memory used by a an application after it closes :?
I don't blame the universal, the hardware is fine and I'm quite happy with it. I do however blame Microsoft. WM5 is just soooo slow. If I didn't do all the performance tweaks that's been discussed here, I don't think I can live with this device. You have to understand that I come from using 3 generations of Palm devices previously, and even though they are using much slower processors, they are waaay more responsive than WM5.
The last Palm I used was the Sony Clie NX70. I used it for 2 years without having to do ROM upgrades, etc. and it worked just fine. One would think that given the number of years that Microsoft had to improve WM, that they would be able to do a better job. As it is now, I'm finding all kinds of weird bugs all over.
Well, I'm just frustrated, sorry for ranting :lol:

I have been making the same point - M$ should know better and memory management is not bleeding egde tech. My Symbian devices have rock solid memory management, they just keep running for weeks and months without the need for a reset. For a US$1000 we should expect better quality all round. Lets hope in te next 6 months we finally get what we paid for.

I sure hope someone here can figure out a hack to fix this soon, cause as it is now, I'm having to soft reset at least once a day, quite often more.
Can any users here who are NOT experiencing the memory leak issues come forward ? I think we would all like to know what we're doing differently that might be causing the memory leaks ...

Hi chtan!
Is it possible to ask you to backup your registry to a file and upload here?
Just to see what is different in your system than ours.
And which is your ROM and ExtendedROM version?

Hi Guys,
The above phenomenon is due to the reason that now we all have data in the flash memory.I was using earlier Nokia Symbian phones, viz 6600,9500...in all these the same used to happen and I had to restart the device...but there are 3rd party softwares, which compress the RAM if the above thing happens and we are at the initital full RAM memory w/o restarting the device...like Stacker, Switcher etc...similarly we also have "Place Maker" for Smart Phones...to do the same...someone can try this app...or someone can make an app to do the same...I hope this gives some light to solve this problem..

By RAM compression, do you mean an active app that runs in the background to automatically compress stuff in RAM then decompress stuff in the RAM on-the-fly when used ?
If it is what I think it is, I don't think RAM compression is the way to go unless there is absolutely no other solution, cause compression-decompression will have a significant performance impact.
I think it's more important to get to the root of the problem
NO.
There are many applications for PC which make the RAM free from unused services, applications, files...
Using this method, you don't need to restart your machine.
It worth it for me to push a button or a shortcut to free the memory without a softreset.

No hack or tweak applied, everything in stock condition. This confirmed my suspicious that Exec and I-mate only having this problem and this is due to their highly customized rom set.
That is strange.. I also have Dopod 900 and suffer from the same problem of memory leaks. The first time I got my Dopod 900 with factory default settings and applications, I played with it for 2 days and noticed that the memory went down to 15++ M.
So I would assume that without any 3rd party applications installed, memory leaks problem is there..
Chtan!
Then you could be a magician, because - i think - we all use the ROM with factory settings after a hard reset, and then - same as you -, when we install a lot of different applications and games, we have the memory leak.
So, what about this registry backup for us?
Or can you write it here the apps and games you use?
I have not performed a soft reset for 5 days. I am performing a test on how long my EXEC can last without having to perform a soft reset. I use mine regularly everyday, about an hour on phone calls, 2 hours on browsing using PIE, the usual opening and closing of applications, and I leave it at night charging while playing a DVD on a continuous loop for non-stop movie playback. I do admit the only time I notice slow downs (4 seconds to open an application) is if I leave about 10 open applications at the same time running in the background. That is why I make sure I close all open applications after use using Handy Menu's option to close all. As of now here is my memory allocations:
Storage
Total: 43.72 MB
In use: 14.52 MB
Free: 29.19 MB
Program
Total: 49.93 MB
In use: 30.94 MB
Free : 18.99 MB (with active sync open and running attached to my computer) If I unplugged my EXEC and close active sync, it goes back to 20.19 MB
These are all my open applications and memory usage without any slow downs:
gwes.exe: 7.48 MB
filesys.exe: 2.72 MB
device.exe: 2.43 MB
cprog.exe: 2.33 MB
shell32.exe: 1.43 MB
repllog.exe: 499.69 KB
services.exe: 227.76 KB
tmail.exe: 163.62 KB
connmgr.exe: 131.81 KB
HandyMenu.exe: 123.81 KB
rapiclnt: 115.90 KB
poutlook.exe: 47.90 KB
SDDaemon.exe: 47.90 KB
MemMaid.exe: 23.90 KB
shfind.exe: 19.90 KB
srvtrust.exe: 7.90 KB
NK.EXE: 0 Bytes
Even with these applications open. My EXEC runs fine with no slow downs.
I am happy with my EXEC. Even after 12 hours of continuous Movie playback at night, I don't feel my EXEC over heating. This thing is amazing!

Where has all the RAM in HTC Universal gone to?

The Dopod 900 (HTC Universal) has 64MB RAM. When we do a hard reset and do NOT install the Extended ROM CAB files, the total RAM is about 50MB. Presumably the Windows Mobile OS takes up the missing 14MB RAM. However, the RAM available after a fresh hard reset is only about 30MB over 50MB.
So the question of the day is... who is eating up the 20MB RAM from my PPC Phone. And more importantly, how do I free it up?
Forget RAM. In WM5 you no longer have control over it, and it is not important either since all the data is stored in ROM.
It's used up by the OS for a quiet a few things. File system cache, Frame Buffer, page pool, XIP buffer, Radio stack, DMA buffers etc etc etc. There's a good article on the windows mobile team blog about this: http://blogs.msdn.com/windowsmobile/archive/2005/11/17/494177.aspx
But lbendlin (above) is right, it's storage ROM you need toworry about - and we'r stuffed on this in this ROM too! TC have seen fit to use a fair bit of ROM for the exteded ROM and then have used 2mb of what's left for two HUGE today themes!
Well,
My HTC Universal has more than enough ROM (40MB free after hard reset), provided that I don't install programs.
However, I only have 30MB RAM, and after installing all plug-ins it goes down to 25MB, which I feel is really insufficient to multitask/multiopen a few memory-heavy programs at one go.

Simple questions on memory allocation

It took me a while to realize I'm confused, but it seems I'm confused about Hermes/WM5 memory allocation.
I've been using PocketPC's since PPC2000, there (and in PPC2002, PPC2003) the o/s resides in flash, and RAM is partitioned between storage and program memory. Thus, loading lots of applications to the device reduces the amount of program memory available for actually running programs. Those o/s had a slider to influence the balance of memory allocated.
Since I got my 8525 I've been assuming that it worked the same way, despite the loss of the memory slider. There have always been indications that I was wrong though - I never saw the memory balance shift, and nothing I've done seems to increase the program memory. Even removing several applications from Storage and installing them in Extended ROM didn't help. I'd LIKE to free up more program memory so apps like Mapopolis can use a LOT of it....
My Start->Settings->System->Memory page shows 56.22MB (Total) for Storage and 49.08MB (Total) for Program. When reading about the Samsung "stacked" (aka MCM) processor I realized that none of the variants listed had more than 64MB SDRAM, and 56.22+49.08 > 64!!!
It seems like either "Storage" now equals flash memory (vs volatile RAM in PPC2003 et al.) and/or there's more the 64MB of SDRAM in the Hermes or something. If all 64MB were available I'd expect more Program memory than 49MB....
I'm confused - Can someone explain or point me to an explanation of how the Hermes/WM5 allocates that SDRAM?
TIA,
Richard
Hermes has Samsung KD5657ACA-D090 chip provides 128Mb NAND Flash + 64Mb Mobile SDRAM. See here:

Thanks pof! That's the one I thought it was - but I'm even more confused about the allocation of the 64MB now. If all of it goes to Program, how come I only get 49MB? If it gets split, how come Storage + Program is more than 64MB?
Ugh, I'm confused

These sometimes confuses people...
But, the stated "Storage: 56.96" is the 128MB part, in that resides the whole OS, ExtROM etc. So in the end there is only 56.96 available for the system to use, plus the other installed programs that cuts it down to about 30MB free after a clean boot (that's just the way it is thanks to our lovely microsoft programmers <3)
The thing is that when you boot your device, the machine loads the whole OS to the running program memory and allocates some of it to important system files, that's why there is 48.80 total and then there is the rest running programs that take space, and about 30MB is free after clean boot on my device.
That's the way it has been programmed, mobile device programming is alot frustrating than on desktop PCs, so the memory handling is very important.
And don't mix those two when you said "56.22+49.08 > 64!!!", they are two separate memoryes. (56.xx being the 128 part and 49.xx being the 64 part).
Don't ask why microsoft excluded the memory allocation slider, maybe the older devices and OSs were differently programmed (memory handling).

That much is logical - not all 128MB of the flash is allocated to the file system mounted as "Storage" - clearly some is for Bootloader, Radio, etc.
Are you really saying the OS and user-writable storage share a filesystem? That seems counter-intuitive to me, though presumably there are user-inaccessible flags to prevent over-writing system files. In PPC2003 there was a ROM file system and a RAM filesystem overlaid so they appeared together. You seem to be saying that in WM5 the user filesystem lives in a portion of the flash - unlike a portion of RAM as it did in PPC2000-2003.

So you're saying WM5 hides ~16MB worth of RAM usage? Did PPC2003 execute O/S files in place then? I mean I can see that the o/s and running programs would take up space, but it's unclear to me why WM5 would report total memory lower than 64MB in that case.

Ok, that's got it - the MSDN blog links (that Lurker0 linked http://forum.xda-developers.com/showpost.php?p=1027392) at least squared me away. Lemme see if I can summarize my own questions:
0) Prior to WM5 most of the OS *was* eXecute In Place (XIP) - certainly on the devices I owned. Now most devices do not support XIP for most of the O/S so more RAM is used in general to compensate.
1) Prior to WM5, PocketPC "Storage" *was* in RAM (for user data), with WM5 it's ALL in flash. Thus there's no sense installing to ExtendedROM vs Storage, because you still can't free up any RAM
2) WM5 *does* hide ~15MB of RAM usage - because they want to. So "Program" really is RAM and it's just stupid that reported Total doesn't match physical Total.
I was tainted by my previous PPC exposure I guess. Half the RAM means that Mapopolis for instance will then always be slower on my WM5 device than on my PPC2003 device - half the SDRAM clock speed doesn't help here either (iPAQ 5555 vs Hermes)
Thanks all!
Richard
1. There are still reasons to use Extended ROM instead of the Storage. The Storage is required for many tasks by the OS, it is wise to keep at least some megs of it free. But, as you can read around, not everything is recomennded for installing on a flash card. Here the External ROM can be in help, adding the storage that is always accessible by OS, and is not used by other means.
2. You may call it "hide" but WM5 actually uses it. Well, the way it uses such an amount of RAM makes it hidden from the tools that calculate total available RAM. But that paging pool is a wise solution. For instance, Symbian OS 9.1 phones (S60 3rd edition, UIQ3.0) use RAM uniformly, and, as such, the same 64MB is just not enough for all (OS, built-in apps, user installed apps). WM5, employing the virtual memory, uses RAM a smarter way.

Agreed - by "hide" I simply meant not reporting it. I'd be fine with MS showing 64MB total with 14MB used - I just got thrown by showing 50MB "Total". I grok their rationale for that reporting choice, I just don't agree
As I alluded above, I have a specific target app which performed well on a PPC2003 system with 128MB of RAM and which is performing much slower on a WM5 system with 64MB RAM. Reducing the app's dataset (maps in this case) brings performance back in line, so I believe I have a memory issue. I'm running an older version of the app due to a bug which is still outstanding against the WM5-certified versions, so I'm likely not getting any help the app COULD be giving the OS. Bummer for me
On the plus side, I've learned a bunch about WM5 memory usage which I didn't know yesterday....
Thanks!

oxios hibernate installs OK
I found this description of Oxios :
Oxios Hibernate attempts to release as much memory as possible without damaging the internal state of the Windows Mobile device (Pocket PC or Smartphone).
Oxios CloseApps closes down other applications by sending "Close" messages.
I was interested in if the Oxios realy works right on Polaris, I now what the software does.

This is not an easy one to get, because you have been educated for years of the exact opposite, but I hope I'm able to make all you guys understand:
it is NOT wise to free up RAM. This sounds illogical, but think about it: the purpose of RAM is to have a fast memory available which holds currently running and recently used programs. The probably easiest way to make you understand why its bull to clean up the RAM:
if you "empty" the RAM, 1st of all you do an almost complete write-cycle on the whole RAM which is bad for the hardware itself, it wears out over time
2ndly you wipe the applications you are about to use out of the RAM, so they have to be loaded again from slow memory (eg. ROM) so performance decreases, that what you don't want to happen you actually MAKE it happen...
3rdly RAM is so fast in handling the stuff loaded, you wouldn't notice any load/unload operations in the background
So summed up on the example of Windows Vista: You have learnt over the years, alot of free RAM is important. I agree, with "old" Operating Systems, especially Microsofts, it was. Mainly because they had a totally useless RAM management...
Now with Vista it's different and that Vista uses A LOT of RAM is actually a good thing, not a bad thing. It fills up the RAM with recently used applications, often used applications and applications you might use in the near future to be IMMEDIATELY ready. This actually IS THE PURPOSE OF RAM, "empty" RAM is a useless thing. And if your injection would be: but if the RAM is full, there's no space for an application I use the first time! Right, my answer: the application has to be loaded from HD and the RAM is freed up much more quicker than the EXE can be read from the HD.
The same concept applies to Windows Mobile. And to be honest, the Polaris has so much RAM, why even bother!

A though on making the Tilt 2 faster

As I've been redoing everything on my phone I realized that there is "separate" memory from storage and for program usage (aka the RAM). For storage there is 226MB and for Program there is 187MB.
I was thinking, with 187MB, the phone maxes out pretty quickly with all the stuff running on it, and sense usually tells us that it's above 60%. Well, can't we just reduce the storage memory and use it towards the RAM? To elaborate more, can't we shift the memory for the programs to become say 126MB and make the Program ram into 287MB? I mean I can do with 125MB for programs or even less if I plug in my storage card. Is this even feasible? Also I'm sorry in advance if this is in the wrong section!
this would be great!
Sure i have seen that asked some where before and the answer was no on that occasion
I dont believe that would make the processor work better inside these devices in this case. When programs and such r pulled up, its done in bits and pieces of info from different files within the internal memory. Its like having a file box and having either all of ur files just crammed inside, or having them seperated into "files". That way the programs know which files to open so they can bring up the programs faster instead of having to search through billions of bits they r broken down so the programs know just which files to search in.
I may be wrong, yet thats just my opinion.
Just use the OS and Sense our phones were meant to use; Windows Mobile 6.1 and Sense 2.1.
I never run out of RAM and on a clean reboot with Wisbar running and Sense, it only says I use about 36% RAM.

The phone came with 6.5 and the new sense when I got it, can I downgrade it to 6.1?
It is not possible to use storage memory as RAM.
WM uses Volatile Memory as RAM (like a computer).

Yes u can. Find the specific ROM u would like to use and see if its 6.1 or 6.5. The easiest way to do this is the download number. If it start with 21XXX then its most likely 6.1 if it starts with 23XXX then its most likely 6.5. Now heres where it gets a bit confusing... theres also a 6.5.3 and 6.5.5 ... If u have any questions most of the chefs on here r easy to talk to and will answer any questions u may have. Find a ROM u like, post a question in that forum (look to make sure that question hasnt been answered before u ask it.) and u will get ur answers.

My Viewsonic V37 PDA running WinMo 3 has the ability to do this. There is a slider you can adjust for more RAM and less storage or vice-versa.

Yes because it uses volatile memory for both storage and RAM. The downside of that is whatever data is stored on the memory will be erased unless it is saved elsewhere. That's why they stopped using this technique in 2003.

The OS is loaded into the rest of it.
would a RAM drive be an alternative, and would it help?
Thinking back to pagefiles, and Ram drives on PC's, always increased the functional speed of those machines
How come no one has mentioned Virtual RAM? I suppose using part of the device memory as a temporary space for random access memory and clearing it on boot would work fine? I mean it worked for my ancient Windows 95 box, which had worse specs than my current phone anyways.
I dont use Sense 2.1 or 2.5
SPB Mobile Shell is, IMO, not only better, but a magnitude of times faster, more stable, and better battery life.
Now granted, SPB Mobile Shell has no where NEAR the eye candy that Sense 2.5 (or even 2.1) and all their various customized flavors have.. but thats the bottom line trade off.
You can either get speed, reliability, stability, battery life, or you can get crazy eye candy. You cant get both.
I loaded SPB Mobile Shell using NRG's latest Sense 2.1 build, then disabled Sense. That way, if i need Sense I can switch pretty easily, but after about 3 or 4 days using Mobile Shell, I dont think I'll ever go back.
