Ok so ive rooted this toy, flashed the 1.2ghz kernal and ran quadrant on it. I hit anywhere from 1080 to 1180. Have setcpu on demand at 800 min and 1200 max so why on earth is my rooted nook color running android 2.1 and a flashed 1100mhz kernal hitting wayyyy higher scores? (Around 1280) doesnt seem logical at all. Specially cause this is an actual tablet and thats just a rooted e reader. Did I do something wrong?

Quadrant is a bad benchmark. It weights i/o far too heavily.
The Tabs RFS filesystems bring its Quadrant score way below where it should be, though in actual use it's very fast.
If you move to EXT4, your Quadrant scores will shoot up by around 80%.

O sweet love of mary. 80% you say. Ok ive seen some posts redarding this ext4 thingymabob. Ill check it out. So if im understanding you correctly by changing to this my tab will perform even better than it does now? Or ill just see a genaric increase on this quadrant test that really means nothing? Sorry im noobish lol

Well, my tab is currently on ext4 and my quadrant scores completely destroys my rfs score taken earlier.
However, that said, i don't really feel any performance improvements except the satisfaction knowing that my toy is now on an open and faster file system as opposed to a propriatory and slower one ;-)

Quadrant scores aren't as accurate as people think you know...
Sent from zombie infested Gingerbread.
There's an app called OCLF that will transparently add an EXT4 area on the RFS filesystem without needing to convert the whole thing to EXT4, giving you EXT4 IO performance in an easily installable and reversible way. Probably your best choice for trying it out. Otherwise, for the complete conversion, you could try this Modaco ROM/Kernel, which includes a complete conversion to EXT4.
As far as performance differences go, it makes a huge (10x) difference to the Quadrant IO score (measured before and after figures), but no measurable difference to actual performance (measured real-world usage figures). Some people claim to notice a subjective difference, but I never did.
Im using the modaco rom and kernel with ext4.
And it does make a huge difference. I get around 1800 in quadrant now.

hi,
please be aware that the modaco kernel (rfs/ext4) will not work on CDMA Tabs.
from modaco kernel thread
This kernel is ONLY tested on a UK Galaxy Tab. It MAY work on other GSM Tabs, it almost certainly WON'T work on a CDMA Tab. If you have a non UK Tab and want to test (and know how to flash back to a regular version), then go ahead and report your results. At your own risk.

That's the point!
It makes a huge difference in Quadrant, which is a synthetic benchmark, but far, far less difference in real world usage - hence it is a crap benchmark!
Pre-EXT4 my Tab would pull around 1000 in Quadrant, whereas my Desire HD would pull around 1800. However in real usage, they seem to perform pretty much the same which is not too surprising as they are similarly specified. On EXT4, my Tab pulls around 1800 now, but still performs much like my DHD.
I so wish people would stop bandying about Quadrant scores because they are meaningless.
Regards,
Dave
If you look at the scores in quadrant , they are split by colour so you can see how good the graphics capabilities are for example and compare to other phones. The colour codes are at the bottom of quadrant by the way
Linpack is a better benchmark. Not perfect, but better
Not really - Linpack only tests floating point performance.

Wow, I started a heated discussion lol. Well ive downloaded the one click lag fix but have not applied the ext2 tools as yet. Want to do more reading about it first. Obviously I want my yab to be the best it can be but I surely dont want to make it genericly better at the expence of my video grafix as one user said he suffered in that thread.

Taking Quadrant scores aside, when I made the switch from CF-Root to the Ext4 MCK, I really did notice a huge improvement in real world usage. I'm not sure if it is really because of the change in file system, but nevertheless thats the only big thing present in that kernel aside from CWM.
Everything said make sense and seems to be valid but let me share my experience.
I have Samsung Galaxy Vibrant and T-mobile Tab. Now both are using EXT4 file system and have fully functional recovery allowing for flashing straight from the phone.
Both now have Quanrant score around 1700-1800 and run very smothly.
Is I/O speed important? I think it is very important because task switching requires reading of huge chuncks of memory. Until read operation completed the user is essencially suspended. Multitasking is the major distinction of Android and lags associated with the tasks switching might be the most noticeable issue since its used so much. Converting of the RFS file system to EXT4 practically reduced lags to unnoticeable level. I don't need any better.
Another critical area for I/O is playing video and especially capturing HD video. The latter works only if I set internal storage and shut down all tasks.
This is work in progress but it seems it reached level of usability when most critical bugs eliminated.
It should be noted that the Tab is flashed with Rotohammer KM2 v1 ROM and Paul Obrien's kernel on a top. The kernel contains scripts converting the file system and flashing recovery. This combination works well, no issues so far.
Well I decided to give it a try and after install my quadrant is 2556 and linpack is 16.865 mflops at 1200mhz. Good scores but just numbers. I do however believe im seeing a bit of snap that I didnt have before when accessing my library. Still really unsure if this is a good thing as im not sure if I can use apps to sd anymore so I may uninstall at some point in the future but thanks to all you who helped the old man out. Atm im quite happy
Now lets get ta craka lackin on a 1.5 ghz update for our tabs

Overclocking will raise processor/RAM heat dissipation and thus might lead to a catastrophic failure. It would be great to have temperature sensor on the board or at least measure current consumption from the battery but it is not easy.
Of course im a pushin lol. Only way to achieve is to try. Course ive read about the tab proccessor being able to handle 1.4 stable and can handle 1.6... Not that id know about these things first hand. Just taking the words of better men.

Doesn't matter what Rom I'm on, cleanrom, aokp, stock, even after I close all apps and services all task managers tell me I am using at least 1gb
ALWAYS
Is this normal?
Use the search function on these forums
I'd try 4.2.2 stock, I have around 400-500MB usage idle. On 4.2.1 (stock and custom) I had way higher usage though (700MB-1GB).
On 4.2.2 though I seem to have only 1.2GB of usable RAM whereas 4.2.1 had 1.6GB
I'm no pro, but if RAM 'disappeared' maybe it got reserved as GPU memory? And the GPU using it's own pool now would explain why you have less used up in general.

Well the N10 is advertised to have 2GB of RAM. Prior to 4.2.2, we had 1.6GB usable, with the other 400MB or so (from what I hear) reserved for the GPU already. Now after 4.2.2, there's 1.2GB usable.
May as well just sold it as a 1GB device at this point... lol

Hmm, the only other device that comes close to this behavior that I've seen is the Galaxy Tab 2 7.0 (stated 1GB, has around 600MB usable). The display isn't nearly HD on that (1024x600 I think) so I really can't think of an actual reason for the 400MB loss there.
A Galaxy Prevail I have shows about 235MB usable, with 384MB stated.
Can't recall numbers on the Nexus 7 or Galaxy Tab 7 though, but I really don't recall memory usage/free being of a concern.

And the device does have 2gb RAM. You should know by now that the RAM in phones and tablets is versatile and used for more than just user space.
One could easily argue the counterpoint of yours, which is that 2gb of RAM means more for the GPU while still keeping a respectable amount for the user. But obviously, you need to do your research when buying.

With some simple init.d and sysctl.conf tweaks you can have complete control over how the RAM is used. Search is your friend. Or at least it should be. LOL
It has to share ram with the GPU. This is monster resolution screen... Did you think it would have as much ram usable as a 720p screen? There's a lot going on at all times with this hardware because of the screen. Remember that ram is worthless if its not being used.
Sent from my Nexus 4 using xda premium
They just released the updated kernel source for 4.2.2 for the N10 and there is a change where they up the ram reserved for the GPU by 384mb. The comment says they did this as otherwise when the GPU needed more ram it would cause fragmentation of the user space ram.

The answer to why the total ram availible has decreased has been solved - Read gzub post.
Called it re-allocated, free'd up or locked, The GPU now has 800mb in 4.2.2 all to its self, where as before it had half that. So in running apps you will only see a total of around 1.2gb.
moving on...
I have a similar issue as the OP.
Sitting idle its running at around 400-500mb used but can, and often does, spike up to over a gb which causes it to not function correctly (Chrome especially seems to throw a massive wobbler and never stay open). I have nothing different installed than I have on my N7 or S3. I mainly use it for browsing, email. If I check running apps there is nothing else there above what was there when it was idling at around 400-500mb.
I have tried a factory reset and the issue still persists. Next step is to roll back to 4.2.1 to see if I can get the stability back as I didn't have these issues on 4.2.1.

Sounds you might be suffering from the same thing as I have since I got my N10.
I don't know how many have this or has noticed it but after a while the amount of free memory just starts disappearing and no matter what you do, you don't seem to be able to recover it unless you reboot. And when the memory gets low enough, the device soft reboots itself. I still haven't found the cause of this but I have finally found where all the memory is going. It turns out that it's the surfaceflinger process that hogs the memory. I started checking when I was running low on memory and surfaceflinger was at that point using over 400MB of it. My suspicion was confirmed when I rebooted and noticed that it went down to around 25MB and now after a while of usage, it has slowly climbed to 50MB.
It would be great if some developer could take a look at this in order to try to fix it.

It's a system process out of /system/bin/. Check your app to see if it's hiding system processes. Most of the process viewing apps/loggers hide system processes by default.
SurfaceFlinger is Androids compositor: http://stackoverflow.com/questions/5699107/android-surfaceflinger
SurfaceFlinger shouldn't stay open though. Everytime I've seen it in OS Monitor the process lasts less than a second and disappears. Something he's running, or the ROM he's using is keeping it open for whatever reason..

I noticed it with the "ps" terminal command. Currently I'm running Aokp but before that I was running stock. I'm suspecting the aosp browser or flash being the cause but I can't confirm it.
EDIT: surfaceflinger is shown in OS Monitor all the time but with ps I can see the amount of memory it is using.
After some monitoring I found nothing. I did a full refresh install of 4.2.2 from the factory image and have installed nothing on top other than applying updates for what comes as standard. After two days of browsing it started to slow down again and show as low memory. I installed a terminal and ran 'PS surfaceflinger', it was showing as using over 600mbs. Stupidly I didn't take a screen dump, but I imagine it will happen again.
Anyone able to shed any light on what's going on here?
Having the same issue
I too have seen surfaceflinger using almost 600MB of RAM. My used RAM was over 1GB and apps were running very sluggish. My SwiftKey keyboard constantly does a soft restart in the middle of typing when the tablet is in this state as well as other apps acting as others have described in this thread. Time for a fix Google!
Ok I've had my phone for two days now and I have been checking the RAM usage on the phone. With 0 applications open my usage is between 1.12 and 1.25 GB out of 1.78GB total. When I have a few apps open it can easily go up to 1.55GB. Is this normal for the galaxy S4?

Is this phone stock? I'm worried theres something wrong with my RAM.
I'm getting the same high memory usage on rooted/debloated stock. It doesn't seem to have an ill effect on the device. It still runs very smooth.
There can be two reasons
1. Memory Leak
2. Proper utilization of the free space in RAM
If the phone is running properly without any stability problems then, Memory Leak is hardly the reason.
This brings to the next reason. We have 2gig RAM in S4. If it had to use only 500 MB or so, then the rest of 1.5 gig wud be for nothing. One shud be happy that the free space is being used for some performance rather than staying useless.
Moreover Samsung clearly mentions that the even applications are not running they are loaded in RAM so that they can be opened quickly. So, I think we shud just trust Samsung or the developers on this.
And another thing, I dont think we shud be worrying about the RAM usage unless we have unstability problems. Let Android handle the RAM.

Free RAM doesn't buy you anything in Android. In fact you want Android to use memory.
Don't worry about how much RAM is being used, concentrate on how responsive your device is.

Is anyone else finding that apps are reloading more frequently? What's the standard limit? I had about 6 apps in my recent and a few of them had to reload upon selecting them from the list. A quick look at the free RAM is somewhere in the 700 MB ballpark. I don't recall this happening before as much.
User space ram was cut down to 1100mb with the 4.2 update by reserving 800mb for the gpu. The surfaceflinger plague seems to be fixed, we'll have to wait and see if that was the only culprit causing instabilities on our Nexus 10. So far, and this might be a placebo because I did a factory reset, things seem to run fairly OK, there are a few glitches and minor freezes, and yes even though there is plenty of ram, the min free values might need a bit tweaking because apps seem to get killed off for no apparent reason.
I'm guessing that it even might be possible to revert the decision to increase such a huge amount of ram for the gpu, which would leave more free ram for background apps. That is if Google doesn't abandon support for the device all together.

If you don't have init.d active you can adjust them in init.rc without any scripts. I haven't checked but they might be overwritten by ActivityManagerService.java at boot though. That is why I use init.d.

It actually makes sense to have around 1 GB allocated for the GPU considering the resolution of this tablet. The framebuffer alone could saturate most of that in a 3D application running at full res. The Nexus 7 v.2 just about doubled the res and doubled the RAM along with it.

You have a lot of cached apps? Facebook alone can eat up to 100mb
And why do you even worry? N4 has 2gigs of RAM....
When you start out with around 1.8gb of RAM.
Have to deal with the fact that once you get below 500mb of free ram the device turns into a lag fest. Add in the 400mb or so that just running the system uses.
What's funny is the pr crap from Google. Oh we made kitkat to run on lower end devices. We used a crippled nexus 4 with 512 mb or ram. Well they failed. The OS still runs like a three legged dog when it's "low" on ram.
Interesting..
Any way to fix this?
I used greenify on s3 mini.
But I guess I won't be needing that since 2gb of RAM plus snapdragon s4 pro is just too high for phone to lag.
Nexus 4 is still high end phone, right?

When you start out with around 1.8gb of RAM.
Have to deal with the fact that once you get below 500mb of free ram the device turns into a lag fest. Add in the 400mb or so that just running the system uses.
What's funny is the pr crap from Google. Oh we made kitkat to run on lower end devices. We used a crippled nexus 4 with 512 mb or ram. Well they failed. The OS still runs like a three legged dog when it's "low" on ram.

Interesting..
Any way to fix this?
I used greenify on s3 mini.
But I guess I won't be needing that since 2gb of RAM plus snapdragon s4 pro is just too high for phone to lag.

Oh come on guys....it is 2GB of RAM and it is STOCK ANDROID! This is not Touchwiz for you to be scared of running out of memory.
I'm a power user and i have never had more than 1GB of RAM used..... just install greenify and enjoy life
Also, what lag? Only lag you will see is if you feck up your kernel settings, if you turn of 3 cores completely or underclock to 700mhz lol

I'm using CyanogenMod not stock and I don't mind about RAM but it's simply plain weird that s3 mini uses less RAM on same ROM and android version.

What would you do with free RAM instead of using it to cache and run services and system processes? Free RAM is wasted RAM

Is Nexus 4 still considered as HIGH END device?

Read here for more information on Linux system memory usage. It's a bit long, so make a coffee, read slowly and you'll understand why.

Not really. Compared to this year's flagship devices, our nexus 4 cannot be considered as a high end device. Having said that, it still performs really well because of the stock android. Only drawbacks are its camera and battery though.

5 hours of SOT is good for a 2100mah battery....and regarding the phone status, it's still a High end device.
Just because it doesn't work at 2300mhz or that it doesn't have a 1080p display it doesn't mean it's not a high end device.
It performs as a high end device, which is what is important. What is the point of 2.3 Ghz when my N4 can run lag free underclocked at 1.1 Ghz?
It's all marketing

You won't run out of RAM because android went let it happen.
The system / apps uses more than 1gb all the time. There should not be a need for root and greenify etc
You can see lag everywhere. It's there no matter what the die hard android fans say. The launcher lags in the widget selection part. Google plus lags and so on
Its funny how people see what the want to see. Most of the same people are also the ones that move on to the nexus 5 and say wow this is fast, I though the 4 was fast etc. They then immediately see the difference. Something you never hear from anybody going from a iPhone 5 to 5s.
To other posters yes in theory free ram is wasted ram. But it's not wasted ram when you need to keep around 500mb free to keep your system running as it should.
Again. On ios you can run right to you run out of RAM and make the app crash. You won't notice it until happens. On Android... Oh crap. There goes the lag fast. Clear all greenify and so on. All while having more than 400mb of free available ram. Which is more than you would have on a system with only 512 mb.

Lol what are you talking about
I have no lag....not in G+, nor in Widget drawer.
iOS and Bada OS are similar. Bada 2.0 on my old Wave 3 was iPhone fast, and it only had 512 megs of RAM.
iOSBada & Android work differently.... what i've noticed that these closed source sh1ts have runtime similar to ART, hence they open up apps fast (even the Wave with 1.4 ghz single core & 512mb ram)

Whether it's better or not, I don't know because I don't use CM. Either way, it is good imo. You can try but not all phones are made the same. So, if it is good on mine doesn't mean it's good on yours too. You just need to try it yourself.
Note: If you are using CM, use the CM version.

That is why my friend, read what I said carefully. I did say it performs really well despite not having all those specs you said. 5 hours? Yeah, on wifi I can get up to 7 hours but on 3g connection, not even close to that. Best I can get so far with 3g all the time is 3 hours. That's my opinion anyway, why should we settle on good when it can be great. I hope the next nexus (if google still make it) would have a bigger battery. That's all.
