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

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.

Memory Available on my Vibrant

So i'm not new to smart phones but i'm completely new to android phones (other than having a g1 for two weeks when they originally came out).
I'm using advanced task killer and when I kill the apps it says 0 apps killed 160M memory available but when I used my moms new MTS it said around 250M. Is that right? Am I missing something here?
Also what's the best way to get into rooting/customizing these phones? I've read some of the threads but i'm not exactly sure why I should do it and what exactly it will benefit. Any links or other help would be appreciated
thanks

Bleh, task killers. Not really recommended or needed. Android is very very very good at memory management.
On my Vibrant, I tried opening apps one after the other, and Android started killing older apps at around 65mb free RAM. It didn't go under 60mb. If I install ATK and kill everything I get about ~156mb free, this is corroborated by Systray Monitor.
The system is still ultra-responsive, even at 60mb free RAM.
Edit: by MTS, do you mean MyTouch Slide? It could be that TouchWiz or other Vibrant-specific system processes (that can't be killed with ATK, thankfully) may use more ram than the Slide's Espresso and system processes.

Yeah I meant MTS.
I was using the app killer more for battery. Does it not affect the battery that much?

No, most of the stuff you're "killing" is just cached and not using any processor power and only a teeny tiny itsy bitsy amount of extra power to keep the RAM refreshed. You might get an extra 5 seconds of battery life per kill, but that's all used up and then some by having to run ATK and hunt it down.
Keep in mind, most of the "Must Have Task Killers" mindset comes from the dated wisdom of old G1 veterans. Those survivors of the 1.x era actually had need of Task Killers because they had devices with very little RAM, a more primitive version of the OS to work with, and less well-behaved applications.
That ain't the case now, and especially not an issue with a Galaxy S variant.

RAM

I have rooted my Asus TF, Put on the H 3.1 os, used Clemsyn Blades kernel, running very nicely. I have rooted it, and uninstalled crap like facebook, books, splashtop etc...lot of useless bloatware is out...However here is the problem........LOW MEMORY....This machine has ram of 1GB, and only 800mb shows, so almost 200 for the GI, and out of that 800, about 400mb is always used, despite using various app killers, I think we should be able to get it to about 200mb used? anyone know where so much of ram is bieng eaten
My question to you great knowledgeable friends is;
1) how to get rid of more useless apps eating memory
2) does using a different launcher reduce ram eating?
3) is it possible to achieve about 200-300mb consistent ram?
This is an awsome machine, I think more tweks we can make is super. I have a Samsung GS2, I have removed most of the stock stuff on it and set up my ownlauncher etc. It runs with amazing memory, 500mb free, and awsome graphics interface. Less nonsense.

If you haven't done so already you could use Titanium Backup to remove more stuff (including system apps) since you're rooted. I would advise caution however in case you remove the wrong thing. Perhaps someone else can post regarding which particular system apps are safe to remove, as I haven't expreimented with this myself.

He could just freeze them first and play with the tf a couple of days and if there are no problems, delete them.
Removing junk isn't a bad thing to do, but in my experience, app killers do more bad than good in android. Other than in windows, you don't need tons of free ram to run apps smoothly. Android has a great ram management that fills your ram with apps for fast access, and closes the least used/needed when another app requests more ram. So if you use an app killer, your tf will have more to do with restarting the apps you just closed and your performance will actually decrease. Google it and you'll know what I mean.

As i said before, much ram usage isn't necessarily a bad thing. It only eats performance if a running app is badly coded and doesn't give its ram free when required. Then you better kill this specific app instead of autokilling stuff. Well coded apps won't eat your performance, no matter how much ram is used.

300Mb oof ram are dedicated to Nvidia Tegra 2. For this reason you read "only" 700Mb. Maybe in near future we will able to allocate more memory than 256Mb to our Tegra 2

memory usage doesn't mean too much now if the app/programe is properly coded, when needed, android should be able to release them on the fly......
same goes to my windows 7 machine, it's got 8 gig memory but the free memory always remains under 500M because the system is using them to cache most recently used applications.
Constantly clearing memory will not help too much, and believe or not, it worsens both the performance and the battery life..
but again, android is not as robust as windows in the terms of memory management, so it's not a bad idea to occasionally take a look at the actual memory usage but just don't go too excessive...

Screwing around with app-killers is never a good idea. Are you actually experiencing issues due to insufficient RAM? I've never had an issue with RAM on my Transformer. Android is much better at handling its memory than people are, let it do its thing.
And for the record, RAM is there to be used. It's the fastest memory a device has, so the more it makes use of, the better. If something else needs more RAM, Android will flush out something that doesn't need it.
I think app-killers are one of the biggest issues with Android, in that people seem to think they're necessary. Unless you actually have some app that's misbehaving or has a memory-leak or something, you shouldn't ever really need to manage your running applications. Just leave it all alone for a while and see how you go.

not at all. The machine is fast, its very quick and loads things quickly. The only time I had problem is using logmein, it crashed and said out of memory...I was a bit perplexed. I cleared a lot on my SGS2, and it was much faster.
Let me know any ideas, otherwise, as suggested, I will see how it goes

From my previous experience with Android devices, it's nearly impossible to increase the amount of free ram. I've tried, and only found one solution that I'll talk about later.
This isn't a bad thing. Ram is not CPU usage, and ram is going to use roughly the same amount of electricity regardless.
What android does is fill up the ram with programs that you will potentially use. That way when you want to use the program, it's already loaded in memory. When you load another program into memory, say a game, it will close apps to make room for the new app.
If you really want more memory, the closest thing is a swap file or partition. I use one on my phone, and it helps a good bit. Don't know if it would help the TF101, since it already has 1GB ram.
If you are still set on more free ram, try a program like auto memory manager (there is also another program very similar, has a blue fish for a logo but I forget the name). This doesn't kill apps in memory. Instead it changes the the when android closes programs in memory based on how much free memory is available and the priority of the program. I used it before on my phone with pretty good success, but now I use a swap file instead.
Right now I don't use a swap file or memory manager on my tf101, sine it runs great without it.

Thanks for all your responses.

I think this article should explain how Android 2.x operates. Even though the article is not about Honeycomb (Android 3.x), I doubt Google has changed how it manages memory in Honeycomb.

[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?

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.

Below a certain threshold of free ram (ie. not enough cached), the device WILL gag...
Hundreds if not thousands of users with 1 GB ram devices use it (Atrix, SGSII, etc.) and I know your phone stutters from time to time with a slight delay when pressing buttons from time to time since that's what my friend's Atrix does.

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...

Below a certain threshold of free ram (ie. not enough cached), the device WILL gag...
Hundreds if not thousands of users with 1 GB ram devices use it (Atrix, SGSII, etc.) and I know your phone stutters from time to time with a slight delay when pressing buttons from time to time since that's what my friend's Atrix does.

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.
And yes, I don't know what "button lag" are you talking about.

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.

I was tempted to stop reading when you admit to not even using it.
If it did the same as AKMO or Auto Memory Manager why on earth would anybody bother.
I sure as hell wouldn't bother writing a 4500+ line script lol.
I totally agree that Android memory is not the same as linux (see my sig) but the similarities are there and the article I posted applies 100%.
Its not about free ram.
Its about the right balance.
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

Well my highly optimized as is but I am aware of V6 and others using it but personally I would stick to my.

Guyzz .... Show your apps list and your ram usage and mention the task killers u use

Take a screen shot of all the installed apps in ur list and also take a screenshot of the ram usage ... Let's see who conserves well .... Mention the task killers ....

I wouldnt recommend "adding" a Task Killer. Better tweak Android's native one to you likings using any of many Tweakers, or manually do so via Build.prop. It has been stated than Android OS does a great job at this. Task Killers will more likely lag the device and eat up resources/battery.
- Paul

Task killer was actually useful back in Froyo days... Back then Android's memory management isn't that great and very prone to lags (I remember my old Froyo phone)
But seriously... we're now at version 4.4.x, no longer 2.2.x... Android has become more and more efficient and even now Kitkat runs on a 512MB RAM device.
If you worry about background apps taking CPU cycles or keeping the device at wakelocks.... Greenify helps... but the ultimate solution is to hunt down the app and uninstall it. It's obvious that the app dev did a horrible job.

+1
I agree...I use Greenify and it helps a lot, airdroid, and even camaras work in the background. I've debloated my Grand, Seeder, done some minor build.prop tweaks (manually): fling speeds, max events, etc, and I have no complaints. Many of those "tweaks" out there, is more 'Snake Oil' than anything else.
