Hi all
Out of curiosity. For those who have some sort of process viewing app in there windows mobile machine.
Does an installed today plugin use any cpu or memory resource if you dont activate them? or do they just use storage.
regards
prysm
storage... yes, with the program installed.
CPU, depends on if they're active... and what they're meant for in general. something that reads or writes constantly will use the CPU.. something that only does that once.. won't.

Can someone explain to me how Program Storage space is allocated.
To the best of my understanding the Kaiser has 128MB RAM for running programs.
However, if I look in the Memory applet it shows TOTAL 95.36MB. I will assume that this is calculating in the base RAM needed to load up the ROM?
So, if I have 95.36 TOTAL it then says I have 35.19 IN USE. This is after shutting down all running programs AND removing everything from the startup menu.
I then go into task manager to look at running tasks and add up all of their memory utilization and only get between 6-7MB. Now I don't totally understand because it looks like things like file system drivers and services are listed here...I would think those things would be included in loading the device itself (and this part of that missing RAM from the 128 as mentioned above).
So with only 6-7MB accounted for in Task manager, what is taking up the remainder of the 35.19MB?
Also, does anyone have any good stats on at what % utilization the device starts to slow down? Theoretically you should be able to run very close to maximum RAM (assuming all needed apps are open).
And, another question out of curiosity is what do most people have for their base utilized RAM on a clean reboot? By this I mean you would have all your services loaded (BT, voice command, touchflo, etc.) and all your necessary today plugins, menu shells etc, but NOT applications like PIE or TCPMP. I find that mine tends to be in the 60%+ range as of right now.
Thanks for any info you can give!
Ok.. I just realized that the Task Manager had additonal tabs that I didn't see...specifically services. Now on a WindowsXP system running services will also usually list a corresponding process that shows RAM utilization. WM doesn't seem to show that information.
So it's entirely possible that all my missing RAM is taken up by additional running services. Any application that will fully detail this out for me?
Also, is there a list of services somewhere? I often go into my XP machine and disable any extraneous services... can I do the same in WM?
thx
yes, and there is also the so called "page-pool' that is a sort of cache / buffer.

this is true, the higher your page pull the less ram you will have but the faster your phone will run. i remember back on my wizard i would alway set like a 32(i think it was 32 or mayb 16)mb pagepool so the phone would run super fast. but at the same time i had like 15mb of free ram....i toke a faster phone lol
Ah right the pagepool... and I think dutty's latest uses a 24MB one which could account for alot of the missing RAM.
Ok...well so here is another question.
Let's say you are running at a high memory utilization....let's say 70-80%
If you could drop that down 10-15% by decreasing your pagepool would that be more efficient? This goes back to my original question of performance as utilization levels increase.
I thought I saw a post somewhere that showed only very minor increases in performance as the pagepool was increased... is it worth that vs. the slowdown (if any) when running at a high utilization?
Originally, a2sd was developed to allow installation of many apps on G1 as G1 has limited memory. The MT3G has more internal memory so it does not need a2sd.
My question is if we can enable a2sd on a MT3G and than use the additional memory for the system. This can improve performance so much ....
Is this possible? I'm a dev, but not on this kind of platform . I know shell scripting, Unix, C so I can help if needed, but don't know how to approach this thing.
Thx.

It depends. Now if you have a 32a board, this is pointless. Unless you have 300+apps installed it will not hurt performance.
I sugest App killer to kill off unused apps that never shut down, it helps so much/
Me really dont need Apsd for mytouch, especially the new 32a boards. Running from the sd card slows everythign down. To improve your performance..
1. Get CPU overclosk from market, set lowest to 386, high to 528 screen on, screen off 256/256.
2. Download swapper, set to size of yoru swap partition etc...
3. Get any free app killer ( ifully suggest Anvanced task killer) and every hour or so, go in and ignore what u use all the time, and kill everything else.
Also, get Cachemate from market or Clean up. this clears out all the garbage.
Doing this, on a good day, my battery lasts 17 hours with data going. and My Live wallpapers never lag
Hi,
Thanks - I already have all that set up. I was thinking on a MOD that will allow improvement of performance in a different way.
My Idea is to actually use the memory that becomes available under /data as we move the app to SD to be used by /system partition. Maybe we can also do a "reverse RAM hack" and increase the 3D RAM.
Again, as I'm not very familiar with the Linux system I don't know how exactly this should be done, or if it can be done at all.
Thanks for the reply though
storage memory in the phone is different then addressable ram.. therefore what your saying is not possible...if you really want something like this set up a swap partition on your sd card.
also task killers are not needed for android... its been well documented here and on other forums as android handles processes much differently than your standard windows box (so no need to have the mindset that background apps are slowing down your system). android itself does an excellent job of managing memory and kills tasks itself when more mem is needed. i used to run ATK myself, and found after removing it my phone actually ran better than killing processes all the time.
your likely just having a placebo affect if you think it speeds up your phone.. however killing process can increase battery life.. albeit only slightly...try it yourself and you will see what im talking about..
regarding task killers, just google it and you will see what im saying...
edit: most roms have cpu scaling in them, if you want an app i find set cpu to be the best, followed by overclock widget...
edit2: forgot to mention autostarts . a great program to edit which programs start up upon boot .. if your still worried about having things running in the background...
I was trying to get a swapfile on /Data (being a lot faster than sdcard, probably), but It didn't work :/
Hi
How can i create Swap Partition for increase RAM on Galaxy tab plus?
I find guide for other device, can`t find for Gt 6200
Thanks for help...

you can;t and should never need to.
You have 1 GB of RAM more than enough for any application.
Swap has not been used since Froyo I think . Since OG phones with 300 mb RAM.
Not used not needed

but this 1GB (830 MB Actually) full after open 4-5 program or 2 game And Android close automatically other Application And last States!
I Want to save last States of other program Anyway until i Close program manually
For example Chrome close tabs after open 4-5 program and when i visit old tabs , it reloaded again!

Hi. Easiest way is to download Swapper2 from the PlayStore.

Only if you want to slow your tablet to a crawl.
Why would you want to swap very fast RAM with very slow SD memory? No need and a really bad idea.

agree. but, it looks like he's more concerned with multitasking.
it always depends on the user. let him try it first and let him decide what's acceptable for him.
Besides, "slow your tablet to a crawl" is an exaggeration.

That won't help multitasking , Android already has an efficient memory management system. That OG swap app was for Froyo phones that only had about 300 mb to run the OS and apps. No longer applies. And since there are no true multi=tasking apps. IE you can;t run two foregrounds apps. ..... , you can never fill up RAM

OK. "Task-Switching" then .
Agree that android memory management is "efficient". the problem is that when it runs out of memory the app at the "back" of the stack gets "killed". data is saved for that app so when it's called back up, it "seems" like it was running all the while.
So, as per the OP question, since his problem was that his web pages keep reloading, ie app was killed due to memory constraints, his idea is to increase the RAM or in this case adding virtual RAM via swap.
It's not a bad Idea, since the amount of RAM is virtually increased, then the amount of apps that can be in RAM at the same time is also increased.
FYI, not only for froyo, i use swap for my NEO V running ICS. made DEAD SPACE run better than without swap. :good:
Haven't encountered a need on the P6200 though. Ofcourse, there must be a reason why 2GB RAM devices are now available.
there is not reason that swapping would make your tablet run better, none.
Because as of ICS , and with 1gb+ ram, you are emulating and interfering with what Android (linux) already does .
you have one foreground task and whatever idle tasks and then unused apps that are retained in RAM until they are needed or another apps needs space and they are removed from RAM. Then they reside on SD memory so what advantage does swapping to SD memory give you, none, in fact it adds a extra useless step .
SO Android attempts to keep RAM 80% used.at all times. If you look at the process logically, I do not believe can lay out a scenario by which the swapper apps beings any benefit to current Android systems.

You actually pointed out the reason why the Original Poster wanted to use swap. he wanted his currently "unused" browser app to reside in ram, and not get killed. in this case it will be in virtual ram.
I agree with all your points. and I don't use swap on my tablet (P6200) haven't had a need, but i do use it on my phone(Neo V, 512 RAM, 384 useable).
All i'm saying is let him try. it's possible that he is hitting the limit on his Tablet. I know, cause it's easy to hit the limit on my phone that i'm very sure swapping works. e.g i can now switch between, Chrome, Facebook, Email, What'sUp, answer a phone call, send a text message and come back to Chrome (which has three open tabs BTW) without Chrome "reloading" those same three tabs. i wasn't able to do this before i starter using swap.
and yes, there's a bit lag but it's better than incurring cost of reloading a page each time, esp if your on a limited data plan.
One other thing that was not considered yet also are the OOM groups and Minfree. another option is Compcache.
The use of Swap really depends on the user and the way he uses his device. You can only see a benefit from swap if you consistently use up all your RAM. Which, if i understand the OP's problem correctly, is the case.
Hi friends,
I believe the consensus around here is that the tf700 has terribly slow internal storage, which causes a lot of performance issues, especially when a lot of apps are running. As such, I would like to know if there is any app that can allow me to see in real time what apps are accessing the internal storage? I am looking for something like Windows Task Manager, which allows you to see all current running programs and their respective I/O operations.
Thanks for your help.
Hey,
I'm the owner of a Nexus 9 and while thinking once again about it's memory problems I started to wonder:
Why is it that Android has to kill apps when running out of memory, yet PCs can keep running all the apps they want even if their combined memory usage exceeds the PC's RAM?
I have never seen a PC kill a program because of low memory, they just become slower.
Thanks,
Niko

Low Memory Killer (LMK) is a feature in Linux Kernel on Android that automatically clears memory when it reaches the limit that set before, caused the memory to be freed and to be able to use by other apps.
It's different from out of memory (OOM) killer, since it will kill all apps when the system is out of memory, thus can cause crashes here and there.
