Hello world,
I have been using several ROMs for my 16GB Nexus 4 and I have a complain about RAM usage: it is never close to its full potential.
I did the following experiment: I opened up lots of apps(dialer, messaging, browser, facebook etc) not very demanding the ram usage was about 50-60% and most of the apps were loaded in RAM as there was no latency in switching between them. The I've opened up GTA 3. And the RAM usage was barely around 60-65%. Overall not much of an increase. I figured out that even though I had over 30% free RAM and android killed my other apps because even though they were in Recents it took the same time to open up.
So my QUESTION is: Is there any way to enable agressive multi tasking (90-95% ram usage) or a way to disable android task killimg mecanics in order to achieve a higher number of apps loaded in ram, therfore improving the overall speed?
Now I am running PSX ROM with S4 patch and Neo kernel
Peace
You can look into supercharging and adding swap or compcache/zram
Depending on how you use your phone will tell you if any of this will help or hinder your device

Thanks for the tips, but I want app switching to be fast, therfore no ZRam. As far as I know zram is slow virtual ram that allows many apps to stay in "memory" but switching to them is not fast. If I am getting something wrong, please tell me. Also I want to use the full potential of my RAM not having maximum 65% in high stress situations.
Try tweaking minfree values, google android ram minfree to get a better concept of it.
Basically its to adjust the number of pages at wich the system will start killing apps/processes with a given priority (foreground, background, services, system, etc).

Higher minram=killing tasks much often, right?

Yes, exactly that. So keep minfree as low as posible, but still give system core processes the priority. This way, ram will have to be really full (really low free ram) for apps to get killed.

The OS e.g. Android and Touchwiz use up about 100mb RAM for itself leaving only 300-400mb for the user. My HTC Desire S has 768mb but really i can only use 623mb hope this helps.

Is there a way to install a mod to free up some of the RAM the OS uses? Or a lighter android that doesn't use quite as much?

I would recommend a 3rd party launcher like ADW Launcher on Android market very light weight, also a app like memory booster which frees RAM. Their are no such mods to change the file system usage as changing the amount of RAM the system needs could result in a unstable device. I have a Galaxy wifi 5.0 with 512mb RAM and the 200mb left is enough for me without lag etc. hope this helps
I recommend using Advanced Task Killer. It has a very easy interface, and frees up ram quickly.
What does it say for ram on the player.... I have seen 377... and 345.
I have 345 and Im pretty pissed about it.
I have 342mb of RAM available. But I heard that around 100+ mb are dedicated to the gpu on the galaxy s phone, and the galaxy player has the same hardware so should be the same. So I think it still has 512mb of ram, but just 342 is usable by Android.
Have a look at the output of dmesg (e.g. run the following in a terminal and copy the resultant file to your PC to view: dmesg > dmesg_output.txt) and it tells you how much memory you have and how much has been set aside. Note you will probably want to reboot before you do this as otherwise the interesting messages have scrolled out of the kernel message buffer.
I've been using an app called Fast Reboot Pro. It appears to simply close processes that are running in the background. It then shows you how much memory was was freed. I hit every so often and especially when things appear to lag. Seem to work pretty well.

Gingerbread/Samsung has it's own task manager which in turn has it's own widget which does this. No need to install an app for this
I to use fast reboot, find it much more effective than what the player comes with. I also use ram manager pro witch is a very good tool to set different ram profiles, I like "balance (more free memory)" the best. I first select my profile, then I run fast reboot, very effective! The more you run fast reboot, the more memory it frees up, witch is great for big games like asphalt 6. Also, I use zeam launcher, very lightweight, perhaps the lightest, but still a great improvement over touchwiz. Another thing, NO LIVE WALLPAPERS is an absolute necessary! These things eat WAY more ram than they say on taskmanager. THEY CAN EAT 50+ MB OF RAM!! Also, services like widgetlockscreen and such will eat your ram. If you want to play a heavy game, go to running services and kill as many as you can, you can also clear cached apps by hitting the menu button in running services. Hope these tips help you to make the most of our small supply of ram!
Hmm, after more testing, it would appear that wifi burns around 25mb of ram when on! So, if your really short on ram, just turn on airplane mode to kill all antennas. I just played modern combat 3 with 25mb free ram throughout the whole level I had 190mb free originally, that game sure eats the stuff :s The CPU rides at 1000mhz through the whole game, lol, could always use some more of that stuff! That's what oc is for
I'm running dagr8s alpha 2 ics rom. And I know that it has lower ram than the gb roms. But lately I have been running Tasker (amazing app btw) numbers and it keeps notifying me that I have low ram and it might not work properly. I go to applications in settings and check my ram and it says I only have 98mb free. I end all tasks and clear ram and then still I have like 120-130 free. I'm afraid that this is a too low amount. And wanted your opinions on what I should do. Is this enough should I just ignore the warnings will Tasker still run fine? How can I get more ram? Are any of you also experiencing low ram?

If you go to developer options in settings at the bottom and select the background processes and set it to 3 processes at most that helps alot...also if u change ur dalvik heap to 64 that also helps a ton...DO NOT and I repeat do not set it below 64 as u will soft brick your phone

You must understand how Android uses memory, it loads your frequentlyused programs into ram so when you go to use them, they open much faster than if they would if they had to open "fresh" each time.the lmk (low memory killer) should take care of everything if you ate currently using a process that uses a lot of memory it will kill off apps as it needs to.
Put simply: FREE RAM IS WASTED RAM.
Have a marine navigation program "Navionics USA EAST" that wouldn't open in ICS(leak and Saurom) unless I cleared RAM. No issue onstock GB, and runs fine on sgh-i777 ICS? Tried debloating leak, but didn't help much. Will try limiting running programs when back on ICS.

Free Ram is wasted ram. Never thought about it like that. I understand but i would still like some free ram just so its available for other apps i open. I did use the task manager to kill running apps and clear ram and it didnt free up that much ram that is why i was worried.
Ill try limiting background proccess to .
Also how do i set dalvik heap to 64? And what exactly does this accomplish?
Thanks for the replies guys.
Yes set it to 3 processes at most. Task manaher killers r just crap dnt use them

Welcome to ICS. This is exactly why I DONT like ICS - the memory footprint is huge just for ICS alone.
Free ram is not entirely wasted ram.
Let me explain.
So, my phone RAM is completely (or nearly) filled and I open a new app. There is now a long delay as Android goes to work closing app(s) down and doing garbage collection to free up memory for the new app I just tried to open but it only frees up enough for the one app I just opened.
And now, every app I go to open is going to have this long delay.
What you really want is about 80% ram usage - enough that there is free ram to open new apps without Android having to scurry around to free up a bunch of memory.
I dont know if there is a way to force a certain amount of ram to be free but imo, thats what youd really want.
I only have 6 user apps on my phone and Im running stock GB so even if I opened everything at once, there would be plenty of ram to have them open all at once (Go Launcher, Blue Skies (paid), Battery Power Widget, System Tuner Pro, BeyondPod, & Audible).
It's called "minfree memory," what you want is an app that will allow you to modify those values. Back when I had a Captivate, I used an app called AutoKiller for that purpose. I haven't needed it on the Note though. You can find it in the Android market.
Is it possible for apps to crash when the phone doesnt have enough free memory (RAM)?
-Once you go NOTE, you'd say 4 inches a Joke
How much RAM do you guys have available when running GB. The phone only sees 767Mb of RAM out of the 1Gb is that normal?
yea i think thats normal because the phone system uses some of that ram to make the phone work. Like if you ever had a sd card or an ipod that was say an 8gb ipod you actually only have like 7.66gb free.
But yeah I would like more ram availabe so the phone can load apps quickly and wont have to waste time closing stuff. I dont think free ram is wasted ram
As said before, Android uses ram differently since it based upon Linux. If the entire ROM runs around 600-800mB and most of it gets loaded into RAM, this will leave you with 400-200mB free RAM but the entire OS is already loaded and ready to go! Once you load a RAM intensive application, Android/Linux kernel will free space for that application.
I believe GPU consumes an excess of RAM to handle this beast's resolution/size.
I have to go back to GB. Delay in apps opening is getting old compared to i777 daily driver.

Thanks for the info, guys.
After using my phone for a while I noticed the RAM is getting smaller, I've used supercharger but the RAM is still the same, and some of my apps is getting force closed. Why is that?
-sorry for the question if it's very noob. thanks.
You don't get more RAM. You can't get more RAM than hardware allows.
Android itself uses part of the RAM, apps use other part, everything over is free.
Supercharger only changes the minfree amounts, that is when Android starts closing apps to free up RAM.

You should then bulletproof only the apps that you dont want to be closed by v6, i.e. widgetlocker/sms apps/etc. That way, it'll free up ram w/out closing necessary apps. It does not increase your maximum ram but it manages it efficiently.

Be careful when using mod of that kind, you will surely get a lot of FC's if you are not familiar with it.
Try to un-install or freeze apps you don't frequently use or as mentioned earlier by bulletproofing apps you don't want to FC.
It always happens that crashes and errors in the system and slow performance are the problems occurred because of the full or nearly full memory. Issue of memory overload the Smartphones are not immune. It can be avoided, if you know how to maintain phone’s storage space. If your phone has large memory then it will run very smoothly.
For performance of the phone to improve you can delete the cache from time to time which in turn will lead to the better performance of the phone. It can be done by using an application Apps2SD which clears both your cache and histories which are not necessary after some time. By clearing cache it frees up the internal space which there by leads to improved performance in the phone.
1.Try turn OFF (a)Sync(b)Wifi(c)GPS by this a constant process will be stopped and which will also improve your battery life and there by making it more use able, bcoz apps like gmail, contacts, maps constantly updates.
2.Uninstall apps which u don't prefer using. Further checking apps which eat more ram is to look in setting/apps/running and try freezing them.
3.Install task manager which provide operation of auto killing of apps in between time interval.
My Config ROM: FXP149-CM10
Kernel : flykernel 0.7a
launcher : ilauncher 2.2.1
Hope this Helps.
what task manager are you using?
it may helpful for some beginner
but i dont think it helps a lot......
just try Ram manager.
if it useful u can buy full version with more flexible option.
It's work for me.

Ok taskmanager are memory hog when coupled with lot of background services eg: widget on screen, social syncing etc.
But if you have organized set of application install with active task managers, it helps solves unecessary lags.

Frequently play games like Asphalt 7, Dead Trigger, ShadowGun DeadZone, Real football, Real Racing, GT Racing, CS Portable.

yes exactly, at the beginning i also tried to use taskmanager, but then i google Android RAM and found guides who say the same. and it seem logic for me. so just let it be. no need to use such apps

first you should check your mobile and wifi signals and stuff like that.

Thats not really true, taskmanagers doesn't make your phone faster, and free ram is not necessarily good, android manages the ram in another way than for an example Windows. Android kills or puts processes in a kind of freezed mode instead of leaving them running all the time, and when a app needs more ram, android will automatically kill apps so that you can play games and so on.
If you want more free ram, you should use Supercharger or Ram Manager Pro instead, because their alot better than using a taskmanager.

Switching off wifi and gps when not in use is just a godamn basic when you use a smartphone, i don't even see the point of opening a topic to say that. Are there still people keeping everything on all the time ?
Task managers are not required since 4.0 at least, if not 2.3 if i remember right. Free ram is useless on Android, i never got this obsession about having free Ram. Many 4.1 and 4.2 custom roms leave less free ram than the official 4.0 and are still way smoother and fast.
This topic is complete bul****, and i'm not even a developer knowing that.
This thread should be moved to /dev/null , because its nothing new in it, and there is alot better tutorials on how to optimize your Xperia Ray.
dont use task managers or killers. Because there is battery drain.

swap ram expander
Adding swap ram (no need for much, 300 to 500 mb is ok) makes such a difference. Since I've started using it, I can multitask and I don't get the big slowdowns I was used to. No blank screen when returing to the launcher or horrible wait times under Chrome. From my experience, Android phones with 512mb of ram generally struggle a lot because they always have to erase and reload ram pages so they don't exceed it. I have a class 10 32gb sd card btw.
no application is running on the background
that's plenty (for an s3)...

The multitasking would be better with 2gb of ram but the phone is still perfectly usable with 1gb.
The galaxy s4 will inevitably have 2gb, just wait until it releases if it's that big of a deal to you.
I can send text messages, make calls and look at porn just fine with 1 gb of ram so I don't feel your pain.

Please stop misrepresenting a microsoft quote in the same way every idiot does on the internet.
Free ram is ram that can be utilised for standby caching and making app starts faster - This is the way microsoft intended this statement to be taken. This "standby RAM" (Cached in task manager) is ready to be released and fill with application data on demand without making other applications page fault.
Ram being utilised by excessively hungry applications is more paging, more thrashing and less performance.
Ram in use by hungry droid apps falls in the latter category.

When RAM starts to fill up in android background processes are cached to the cache partition and because we aren't using a HDD the performance loss is negligible.

I think CM10.1 has more free RAM.
Except when apps in Android are cached they often have to reload when you "switch " back to them. Not really multitasking. It's as if when the app is cached it stores a pointer to what it was doing. I notice a huge difference when I have 400mb free ram, if I only load a few apps they don't get cached and I can switch to them without them reloading. When I have less than 100mb free ram even my desktop gets redrawn, tabling chrome reload etc etc

You sir, are talking out your arse.
When ram fills up on android, processes are either terminated leading to them having to be restarted or pulled from cache, leading to sluggish ui and loading.
