Why auto-killer will NOT speed up your phone

This is for all those people that think auto-killer is the be all and end all of android.
Auto-Killer Does:
Kill Apps to free up RAM
Auto-Killer Does NOT:
Speed up your phone
Here is why!
The way RAM works is - it temporarily stores the files needed to run an application so that the CPU can access them quicker than from ROM/SD-Card.
RAM does NOT slow down when it has more information stored within it, therefore having 20 MB of free ram or 120 MB will make NO difference to the speed of your phone.
Ironically, having more free RAM may even slow down your app loading times because:
If you wish to launch an app and you have 120 MB of free ram with no apps loaded it will have to load the app from your ROM/SD into the RAM and then access it from there.
On the other hand if you have the app already loaded into the RAM, with only 20 MB of free ram, it will load quicker because it doesn't have to check the ROM/SD first!
Therefore, having less RAM free means that more apps will load quicker. In addition to that, Android already has a built in task killer which is designed to kills apps which haven't been used in a long time when you get to a very low ram figure.

Dude, you're talking to deaf ears.
n00bs doesn't care about memory management and schedulers and such stuff... so they do what they always did on their WinMo devices...

I can only hope some listen.

what about task killer is that the same ?
LOL JK

Hmm at about 26 meg left, my phone gets buggy, and slow moving.
'I dont believe appkiller makes my phone is faster, BUT It does´nt get slow...(26meg and lower)
So Autokiller will help my phone having more ram, and the phone is running fine
About the 120 meg free ram, I agree, just use a lower setting

I love the way peoples minds work. Tricks of the mind buddy, tricks of the mind...

Sure, task killers will not speed up your phone, but they will end apps that drain your battery (i.e. facebook, etc.).

I hear what you say and understand what you mean but if that is the case can you explain to me why, after a day or so my phone slows to a crawl and clearing out the memory speeds it up again?

Buggy apps wich leaks memory?

I know technically you are right but my Hero get s laggy once the RAM gets low probably due to to many background tasks running at the same time so `freeing up memory`ie killing background tasks definitely removes the lag and speeds things up again

I have to agree with kilsally here. What you have to think its that the more tasks that is open in the background in memory or not the phone will slow down due to the amount of processors running. Just like a PC the more running the slow that gets. One way to improve this is to increase system memory. In the phones case memory is not upgradable (but would be great if it could be!).
When you end tasks using task killer, it's like ending tasks on a computer and WILL speed it back up again (as there is no/very little processors running to slow it down).
Catch my drift?

its great that theres information out there stating how task killers and android shouldnt play together, but when it comes down to it, advanced task killer pro realllllllyyyyy helps keep my phone speedy. around 20 mb is where my phone gets clammy, around 65 mb is where it grows wings. at the end of the day, if i works for you do it. if not dont. THAT'S the beauty of open source <3

Well thats not really true. Although having 20mb or 120mb RAM free itself will not speed up the phone, when using a task killer to clean up running apps you see the speed increase through the lesser toll on the CPU.
When you close and app in android it very rarely closes (the developer will have to force the phone to close the process thread - its very messy), it goes to 'sleep' this often a good thing as it makes opening the app up again much quicker. however most apps leave background processes running all eating away at a chunk of CPU. using a task killer should providing there are a fair amount of apps running to start with boost the phones performance generally

exactly! background apps doesn't only use your ram. many apps uses the cpu aswell and there for slowing down the phone

which is exactly why when i have around 20mbs of ram left, killing apps makes my phone faster. people are thinking tooooooo technical about it. its not about memory being used, but whats in the memory (app) isnt slowing things down, but the fact that that app is causing cpu strain is!

It depends what you information you want to have 'pushed' to your phone. If you require it to be 'pushed' the app must run in memory to allow this to happen. Task Killer can kill apps that you don't require 'push' information.

I thought android paused cpu threads that wernt in use?
Also, doesnt matter if you have 20MB of free ram or 2TeraByte of free ram.
I've tried with and without task killers,far less problems without, and i felt it was faster without.
this kinda smells like RAM / registry cleaners for Windows, bull**** aimed at non-technical noobies.

How does facebook drain your battery? I run the app from time to time, never changes bettery life. Also the people talking about CPU hogs - most apps go to sleep in the background and do not take up cpu to continue to run (or at least a minimal amount) - if you're running apps which have memory leaks etc then i think you should choose a different app to use instead of relying on a task killer to kill the task every time it goes wrong.

Programs that aren't in use do get 'paused' however nearly any program running needs to maintain some CPU activity to stop it from crashing, and some register services that run in the background aiding the program doing what ever it does, these often don't get stopped.
Reg cleaners on PC's are incredibly useful for older PC's, ones what have had a lot of stuff installed and un-installed, and ones with slower HDD's. Because programs don't always remove any reg entries they put in when installed the registry can become massive, with slower/older PC's that can reduce performance quite a lot because it takes longer to find the things that are required, obviously this won't be a problem on newish PC's (ones with sata or solid state, or even fairly new IDE etc) but ones with old 5400rpm IDE (old laptop drives) drives may struggle a little.

Available Memory

So when im not running anything, when i open Advanced Task Killer it has like 125M is this right???
So what the other 387MB doing?

what I see
when I 1st start I have about 230MB, after a few minutes it goes down to about 90mb...without opening anything...seems many programs on the Samsung "open" by themselves...also, I see that the CPU goes down to about 100Mhz so I keep it at 1000Mhz with setcpu....plus deleted many Samsung apps(about 30MB)...helps with the lag...

Don't worry so much about it. This isn't windows, you don't need to worry about free RAM. Android will kill tasks as needed to free ram when it needs to. Some of that is likely used for disk cache as well. That will also be released as needed. Let the OS do its job, it's quite good at it..
Killing some of the bloatware will help as well, but you need root.
I also think that this phone, like the G1, has some of the speced 512M ram dedicated to the camera, GPU, and other stuff. In the terminal, free shows about 388M as total ram.

is it a good to create a swap partition on the SD card?

Why on earth would you want swap with this much ram? You likely can, with root and swapper, but why? This phone doesn't need it like the G1 did. Swap could help keep more apps open in the background, but there are already a lot of them there. I don't see any benefit to swap right now. What isn't working for you that you think is related to low ram?

[Q] V6 SuperCharger on MyTouch 4G?

It sounds like everyone would benefit from using this script, but there's no specific guidance for the MyTouch 4G. I assume option 8 or 9 would be best since the phone has 512MB of ram.
Are there some roms that we shouldn't be using V6 SuperCharger with?
Link to V6 SuperCharger: http://forum.xda-developers.com/showthread.php?t=991276

You're wrong on 2 points (possibly more):
1) This script is just the same as Autokiller app, with a small addition - it can (or can't) keep launcher in memory. Nothing new and revolutionary. This app exists for a couple of years.
2) This phone has 768MB of RAM. It won't benefit from a low memory killer (or actually, different settings for an existing in OS lowmemkiller), because it has TONS of memory. I just took a look at my phone, ~100MB of memory free, and ~300MB of remaining memory is taken by CACHED apps. If you don't know what it means - please read up on Android memory management, and I'll give you the short version - it's the same as free memory, but better.

It states in the first post:
Also Note: Nothing else does what The V6 SuperCharger does!
................Not AutoKiller Memory Optimizer, Not Auto Memory Manager, Not Minfree Manager...
The Nook Color has 512 MB of ram and people have noticed a big difference using this script on Cyanogenmod.

but since the Glacier has 768MB of ram, you won't notice much change.

I have found it useful on ports and ROMs that aren't tweaked specifically for this phone. For instance, if TDJ made the ROM, V6 is useless. In fact, it will only hurt.

I use this script on my evo and its great so I just rooted this phone and flashed the mik runny ROM, I was using it for a day and only stayed at about 100mb of RAM so I decided to use v6 with option 8 and now it stays around 200mb and is running super smooth.
IDK if that helps any but I always loved v6 and know a few people that use it on a few different phones and it always works for the better.

Why do people that know nothing or close to nothing about OS internals, decide that they have better knowledge of memory management should be, then OS and phone designers? The same people who don't know the difference between cached and active apps, and the only number they understand is the (useless) amount of free memory? I see it all over the forums, and it amazes me each time. How do people actually try to judge if something works well or not, without getting at least some basic understanding of how the things work?
Oh well, here it comes again:
http://forum.xda-developers.com/showthread.php?t=678205
Read this. Maybe you will understand something.
Few, if any, 512MB phones and no 768MB phones need this script, or any kind of tweaking for lowmemkiller values, especially not since Gingerbread and when not running Sense (which retains the ability to cache apps, removed in Gingerbread mostly to ease running the OS on older devices). The only thing it does, is to make garbage collector work harder and kick in earlier. It doesn't make your phone "smoother", and whoever think it does - should check the meaning of the word "placebo" in the nearest dictionary. The number that stands for "free memory" means something between "close to nothing" and "absolutely nothing".
I know I shouldn't be surprised, people always tend to have strong opinions on everything, even things they sometimes don't know a thing about. But still, it's XDA-Developers, not XDA-Phone-users, so at least something should be done about it. Even if the education attempts will fail, like they mostly do.

I do understand that in some cases you don't need a memory manager like if your running a stock ROM or an aosp ROM that doesn't take up as much memory.
Now I haven't had this phone long enough to say if this script is all that good for this phone but I know on the evo running a sense 3.0-3.5 ROM that wasn't meant for the phone and hugs up every little bit of memory that the phone has to offer, this scrip makes those ROMs usable.
Without it or something like it the phone can't handle doing simple tasks like using an app without fc something else like the launcher.
So you could say what you want and yes maybe this phone doesn't need it since it has more RAM and ROM but I'll still try things like this to try and see if it will better the phones performance.
Sorry if that doesn't make sense I'm still half asleep.

The instances where i have noticed that this works is while doing benchmarking with quadrant. It has shown increased framerates for me after running the script and I also get higher scores on quadrant, about 500-1k more than without. I dont know if its usefull for much other than benchmarking though. I think the phone runs fine without it though.

What you have to understand is performance is not measured via syntactic benchmarks (ex: Quadrant). The biggest issue with people is that they don't know enough to know that they don't know, so they compare it with silly numbers (ex: score) they can't comprehend what they see, much less put numbers behind real life activities that's not applicable in controlled environment.
Now far as V6-SC script goes its almost obsolete now due to few things. 1) Hardware advancement where now minimum spec requirements for "SmartPhone" are 1ghz single core proc with 512mb ram. But so called "SuperPhone" now has dual core 1ghz-1.5ghz with 768mb-1gb ram. So it make no sense as we don't use 256-566mhz proc with 64-256mb ram because we are more then enough hardware adequate for heavy daily usage. 2) OS development which elements most of it as hardware is more and more powerful. But on software level mostly all custom base rom (ex: CyanogenMod) is highly optimized and tweaked to run on optimal performance.
Now is it all placebo effect? Mostly, but not all. But does it mean it can't be tweaked any further? (Rhetorical) No. How do I know? We (scope outside of XDA) tweaked it to the next level. How you ask?
1) Optimized ext4fs: reduced r/w rate (healthy NAND lifespan), improved journaling (corrupted data writeback integrity) = Which improves the IOPs and performance access rate.
2) HC3.x fugu binaries, patched sqlite libraries, mSD read ahead buffer fix.
3) Modified VM: OOM (Out Of Memory), LMK (Low Memory Killer), VM heap (Virtual Machine), DRA (Dirty Ratio), DBR (Dirty Background Ratio), DWC (Dirty Writeback Centisecs), DEC (Dirty Expired Centisecs), SWP (Swap), VCP (VFS Cache Pressure).
4) Increased minfree value: Background, Foreground, Empty, Hidden, Visible, Secondary, Content.
5) Optimized cache: File and Drop cache, Forced cache (resident loop).
6) Custom kernel: OC/UC, UV/SVS/VDD, BFS/CFS, RSU/VR/SP supported.
7) Custom ROM: Optimized Rom script and props (ex: CyanogenMod).
I bet my superior MT4G can own your inferior MT4G. Cuz you can't touch this as its tweaked to THE next level. I'll stick with AOSP2.3.7GB until ICS4.X is more stable and we understand more as most memory grouping and adjustments might be changed.

First of all as dev of V6-SC you would be very defensive but at same times your not charging money to normal folks for it is a good thing, so thank you. Which I can say less about other folks editing same value claiming it new. Now I don't know about Jack but let's be clear on few points.
1) I did try your so called script and didn't like the whole script manger + busybox cast AFTER the OS startup. Which normally you can achieve via daemon or init.d script after kernel is initialized by declaring and using native shell. So no need for force apply afterwards as it was utilized before it was initiated via script manager. Also V6-SC couldn't keep the selected category minfree value which changed. But in short I didn't notice anything revolutionary as it was fully optimized long before I randomly landed on Android General section and saw your post claiming it maximize the devices performance. Which I was spectacle about as from your post you did seem to have basic knowledge hopefully not from wiki/google but *nix usr exp before landing on to Android.
2) Like I said I don't know about Jacky Boy but I can GRANTEE you I have NEVER had this so called "button delay" you specified. But I did modify the sampling rate and pressure density accommodated by tweaking transition speed. But now I run min:368mhz/max:1027mhz/gov:SmartAssV2. But even when I was battery conscience before I had MP1650mAh I ran on min:230mhz/max:768mhz/gov:SmartAssV1 with custom -75 to -100 VDD using ~14mA idle and ~60-90mA active per unit scale. I never had lag with 200mb used RAM running at least 18-20pcs and 14-15svc. So what your friend is running (Atrix) is irrelevant also isolated.
3) O-RLY am I really missing out? I think ill stick to my own. But don't take this post personal as it was ment for it to be argumentative. Difference is I actually know what I'm talking about as I have strong backgrounds on...

I didn't need to try it to know. I tried Autokiller, I played with lowmemkiller settings and watched the results, and I did it on Nexus One with 512MB of memory. It never needed anything since Gingerbread, and unless I made the settings super-aggressive, Autokiller actually failed to make any difference whatsoever - the apps were killed based on their age and never dropped by replacing apps.
In the current system, I have 100MB free + 250MB cached apps (which is just the same as free - theoretically and practically). The main difference you're not accounting for is - Android isn't a Linux distro, it's a Linux-derived OS, with many changes for mobile activity, especially on the kernel level, especially in the memory management area. "Linux memory consumption" isn't Android memory consumption, since they manage things differently. Linux isn't build to kill running apps, its lowmemkiller can't do it. Linux doesn't have concurrent garbage collector. Many Linux examples are irrelevant. Cached apps in Android aren't cached pages in Linux, freeing cached pages in Linux isn't killing cached apps in Android, and the most important - "performance degradation" doesn't exist in Android, since you ALWAYS have enough memory for any size of task (the largest loading task requires 50MB of memory, and there's 100MB free on my phone), and concurrent garbage collection is ALWAYS present in the system, the only thing you're doing - is calling it earlier, making it actually work more and getting the system more laggy than it could be.
I understand that you want to protect your creation, but in this case, you're wrong, sorry. You won't convince me.

Sounds like you never got it working properly.
Also, if you have init.d support no need to run anything on boot with script manager.
Maybe the rom's kernel was applying settings late.
And no my friends atrix is not isolated there is a rather big thread in the atrix forums.
SGSII users see benefits too so seems there is always room for improvement.

In fact, many report LESS free ram, ie. better multitasking, along with better performance and smoother performance.
Because I don't think Android memory should work the same as linux memory either.
Also, you tried AKMO because you felt there could be improvement and it didn't work.
THAT'S why I wrote a 4500+ line script that blows anything else out of the water

Sounds like you never got it working properly.
Also, if you have init.d support no need to run anything on boot with script manager.
Maybe the rom's kernel was applying settings late.
And no my friends atrix is not isolated there is a rather big thread in the atrix forums.
SGSII users see benefits too so seems there is always room for improvement.

[Q] RAM manager

Hi,
I looked at my free ram and on daily use I have 1 GB of free ram.
So is there any sens to use ram manger to allow android use more ram (mean to not kill app and has less free ram)?

Unused RAM is wasted RAM (just before anyone else says it )
I have 1.3GB of RAM free on my N4. I wouldn't recommend a 3rd-party RAM manager, and just trust Android to handle it
Unrelated, but I have some weird memory leak issue on my N10 that basically causes all RAM to be taken up by something eventually, and all apps end up Restarting. Quite annoying, but the only thing I can do in this situation is reboot the tablet. Can't say I've seen or heard of this on the N4.

i cant say i like the way android does it, even though it does do it. i use greenify, and autostarts to prevent apps from starting in the background. also, i change the numbers to androids ram management. now im happy

But greenify make some apps start slower, yes? (because they have to start again)
How you change the number of free ram?

If you have widgets on your lock screen or on your home screen they will use up ram. Uninstall any apps you rarely use to free up ram.

Don't see why you're worried. You have as much FREE ram as an s3 does on the box
On a more serious note, I doubt you'll see any difference by freeing up ram. 500-600 mb of free ram = smooth experience generally

I'm no expert, but what I've read on these forums, it's best to just let Android take care of it. Android has come pretty far with memory management, and third-party apps might just end up taking more RAM/battery.

You're wasting your time worrying about it.

This is true, forget about ram manager and dont be paranoid about the free/used ram amout

Thanks for help, I will not use any ram manager etc.

[Q] RAM on I9505

Hello guys,
i can't understand where disappear 2Gb memory on SGS4 i9505. I use stock ROM, minimum one time per day i need clean memory through "active aplication" manager because phone unresponsive, it is same situation as on my old phone SGS1 I9000 (512mb RAM). Even all aplication cleared still used 1.2Gb RAM of 1.78Gb physically memory. This is normal or i need begin flash a lot of custom ROM's for find something useful that realy works??? What is better way?
Thanks in advance for answers.

Stock ROM is full of bloatware and stuff. This means you have a ****load of useless apps running in the background, and some useful ones too. You should root your phone, go to application manager and DISABLE all of the useless bloatware you never use (use caution though - some things depend on others. For example don't disable google services if you intend on using any of their things).
There are many apps out there which show you what's running in the background and taking most space. Are you sure your phone feels slower or it's just the RAM that worries you?
Keep in mind that apps keep running in the background so you can later open them quickly, so if you force close them the next time you open them it will be slower.

Yes, i feel that phone slower, i wait too long time, while i check RAM it is almost full, and after cleaning RAM phone is more responsive.
Ok, i'll try disable some services in background with root phone, thank you.

I'm still using mine on the unbranded MDM which came with the phone.
I will wait a couple more days, and if they will not release a BTU update, i will flash the DBT one.
Since i have the phone ~May , i never had those lags and redraws like i see here from some users.
I'm not rooted at the moment and if i use apps/games and i just exit them, used RAM drops to ~0.98, i never clear them from memory, but if i do then the used ram drops to ~0.87.

let the android system manage your ram.
any way, you want to see more free ram?
go to developers options and set "Background process limit" to 4 or less

Do you recommend doing this for battery life improvement?

it saves a little bit of battery.
but setting limit is not so good for multi-tasking, some apps (not cached in the background) will take a little more time to open, maybe you will not notice that. so if you set limit for example to 2, open running app in setting and press on "show cached process", you will see only 2 apps are cached in the background

Yes, i did it, now on phone "Background proccess limit" is 4 app, but in any case during normal phone job 1.1Gb is used.
Simply i compare with my previous phone galaxy s I9000 that flashed with custom ROM on android 4.1 (comparable software) and i it perfectly and stable work with 512Mb RAM and 1gb (one core) proccessor. I don't play with games and don't feel high difference between two absolutely different hardware's & devices (i don't speak about screens). Old phone work very smoothly, it only uses half as much system resources relatively to new galaxy s4 i9505. Why i need use "Background process limit" option on newest device with 2Gb RAM, even think about it? What is payment for biggest high quality screen?

no need and not mandatory to set process limit, it is for dev and testing purposes.
linux is smart enough to manage ram

Of course, but what reason unrational using memory on galaxy S4?
I can understand than system use 500Mb RAM even 700Mb but not over 1gb....

on S4, for example, you are dealing with almost 1.14 GB of system apps,
a lot of bloatwares....

So, only one way remove excess system apps.
