Well, my tf101 is transfering data to the internal storage (/sdcard) at very slow speeds. Antutu is reporting Write speed of 4.5-8MB/s and Reed speeds of 19-22MB/sec.
This seems pretty bad in general, but my Rezound with similar specs is getting ~20MB/sec write speeds and it just says ">50MB/sec" Read speeds and doesn't even bother to give an actual value...
anybody know of any scripts, tweaks, mods, anything to improve the situation?
it is beause of the partitioning in honeycomb. The more data you have the lower the speed you can mess around with system tuner to get a better value though

Can you clarify at all? How does the partitioning differ? I was getting speeds like that on my Rezound when it was running Android 2.3.4 Gingerbread, and now its running 4.0.1 and still getting much faster speeds than my TF. How is the partitioning in Honeycomb somehow affecting the transfer speed if a previous version of Android didn't exhibit this issue?...

You could try slightly bumping up the read ahead on each memory block might help performance not so much speeds
blck0-1024kb
blck1-2048kb
Would be a start atleast hope it helps

I have done the manual ICS update 4.04 that was recently released in the general section of the forum, and I noticed that the memory is much lower compared to 2.3.6. The memory averages around 50MB, sometimes 100MB, and showing used memory around 285MB. I was wondering if this is normal as some of my games force closes after i start to play. the games uses quite of bit of my phone's resources and was working perfectly on 2.3.6. Also, i use the GO Launcher EX and i tried not using the launcher, but it only frees up little bit of memory. My phone is not rooted, everything is stock of course. I was wondering if anyone else has the same or similar problems? or is this normal in terms of the ICS OS using more memory?
anyone knows????
Give me a list of what services are running and how much ram they're using. This is done through settings > apps > running.
The same is the case with my phone. Sadly thats a compromise for ICS, you have to install custom rom to free up more memory.
I had the same problem at first .
you have to install a ROM+KERNEL that support BIGMEM.
I use Pixel Rom 1.72+ Airkernel 3.9.5, I now have 180mb+ with many programs running. its super fast/stable
Try and you wont regret

i was actually looking into that ROM and kernel. How is it in terms of performance and battery life. I'm looking for a ROM and Kernel that increases both lol.
Also right now it says 292MB used and 46MB free. the processes running are settings (34MB), go weather (4.9MB) go launcher ex(34MB), go sms pro(7.5MB), go switch widget (4.1MB), google services (8.5MB), android keyboard (11MB)
Also for extra info, here is cached processes:
go weather (4.8MB) launcher (14MB), media (5.1MB), my uploads(3.4MB), package access helper (3.5MB)
in total, including cached processes, 134.8 MB used
You're sure that is everything that is being shown in the two pages? If so, it looks like something in the background likes eating RAM and doesn't want to share.
Regardless, could you download terminal emulator or something similar (or just use adb shell) and type: "ps > /sdcard/ps.txt" and upload/copypaste the file/contents. It's not a particularly great way of figuring out memory usage but i can probably make do and see if something is wasting it. I know on a fresh boot i have much more lying around in the cache than that, without opening any apps - mostly google sutff.
E.g., 24MB launcher, 11mb core apps, 15mb maps (and more in running), 36mb play store and so on. Although currently on ~402mb bigmem, i don't remember it being much less before - still 200mb used (as always) and cache is generally filled to the brim.

Hi. I have the same memory problem, i created the ps.txt. I don't know how to read this txt..
What does mean these things :
USER PID PPID VSIZE RSS WCHAN PC NAME
What are ppid, vsize, rss wchan??
Envoyé depuis mon Nexus S avec Tapatalk
PID -> Process IDentifier -> Wiki for more info
Vsize -> Virtual Size -> RAM usage (SWAP + Physical)
RSS -> Residential Set Size -> RAM usage (Physical only)
wchan -> Some waiting indicator, never looked into it
I just want a detailed list of what processes are using up the RAM. Basically i'm looking for something with excessively high RSS and just comparing it with my phones results.

Too sleepy (and mentally deprived) at the moment to give a good answer. I would, however, try ditching go launcher altogether (preferably uninstall, hopefully not too much trouble) for a little while and see if it gets better. I can't tell for sure without better memory analyzers but it is possible golauncher has gone haywire (or maybe not, trial and error ).
If not this, i notice there are many kcryptd processes going on. To my knowledge that is kernel based but i know not what it does or what it's for, did you encrypt the phone by any chance? I havn't run stock in too long to remember how the ps list was. I should be able to give a better, more thorough answer tomorrow regardless though.
edit: also, i've attached my own ps log for reference. We're talking around 205mb used and 197mb free when that log was taken. Have a look. Note that RSS (all in kB) can be shared, so that 20mb from each go launcher process may well be the same ~20mb between all of them which they all have access to, so it's not 100mb+ used, just ~20mb.
I'm pretty sure I haven't encrypted anything, is there a way to find out what has been encrypted? I have removed go launcher ex and the themes. Will now see how the memory is, in the meantime, go sleep Harbb lol.

Wow I'll have to try that pixelrom and airkernel for sure (especially since I just recently rooted for the first time a couple days ago).
The miniscule account of RAM we have on our phones to play with is literally my only complaint about my Nexus S. If I could seriously UP the free/available RAM like ismailham says, I'd be falling in love with my phone all over again!

Definitely non issue. Done it to send mine for repair for a failing BGA, it was near painless. The biggest "trouble" was removing CWM and SU to make it look stock.

Battery was very consumable, i/2 day for full recharge, maybe it is happen because data transfer for sync enable. And it is still slowly, maybe because i have install about 15 application from marketplace. But it is all good for me, and i still waiting for new complete for this build with more fixed. it is possible if to be NAND version make this build faster than SDCARD?
Sorry for my bad english.

Bluetooth does not work well for many people. It takes me 10 attempts to pair my headset. - known issue
Battery life is not great (or super accurate) with this rom. You would be better off with http://forum.xda-developers.com/showthread.php?t=1347321 if battery life is important. It has a better battery driver.
Sd cards and Nand have about the same speed depending on your SD card. The SD card has to have high random read/write abilities, or the experience will be bad.

Thank's wizardknight, I'll try your trick and give my review next. But if this built have no different between SDCARD or NAND, absolutely we will choose the SD CARD because it's more save if anything happen. that in my opinion. And i will use this built in my phone.
Thanks.
Thank you wizardknight for your suggestion with sd boot, it is make my speed increase well. Only when this phone sync come slowly, but back to normal. I use vgen 8gb, I did not know the read and write speed.
Still waiting for bluetooth fix and final release for this build from arrrggghhh...

No one is developing bluetooth, and no one has for quite awhile. What you see is probably what you will get. There has not been any new news in a few months. But we keep hoping
Can someone tell me, how the hell can i make faster the transfer speed on miui 2.7.6? I install the app from playstore call Multi Mount SD Card and mount correctly my 2 sd card but always the transfer speed its so slow!! I cant even copy a file of 10mb bcuz of it! the must irritating its when i switch to my old captivate with ics! everything it so smooth and fast, can someone recommend me a ics rom that support aprox. 350 apps and keep running without much lags, bcuz when i install the half of apps it became so laggy to the point that you cant make a single call and needs wipe! even on gingerbread! I try uniporn and i didnt like bcuz i cant play 720p mp4 downloaded from youtube. someone recommend me remics ux, could this be a fix? What do you say?
Wtf are you doing with 350 apps? Lol. I don't think any single core phone with <750mb of ram can handle that.
You may want to get a better phone if you doing high end tasks, your only working with a single core cpu, so keep that in mind. Jb's cm9 might be your best bet as it has oc capabilities.

I can't seem to find a definitive answer anywhere as to why our 1 GB RAM only shows up at 669 MB on CM10.1 nightlies. I can understand the ROM requiring some space, but 355 MB seems excessive.
So what's the real deal behind this? Other 1 GB phones seem to still show up with 900+ MB in "About Phone" - eg the One X, also using CM10.1.
The reason I am keen to know is because using the default minfree values (I don't really want to have to tweak these), I find apps close WAY too often when something runs in the foreground. I have trimmed down my memory footprint majorly, have only a couple of essential widgets and three home screens. I don't think that in 2013 with a phone that has 1 GB of RAM one should need to minimise things down to one home screen and one widget just to be able to run memory-hungry apps.
So does anyone know why CM10.1 eats all the RAM, how to get it back, or how to stop apps from dying all the time? I can't even get through a 3DMark or Basemark X benchmark without it crashing halfway through due to lack of memory, even with all background apps closed.
Any insight would be much appreciated.
same issues
I have a sgs1 (i9000) and am having exactly the same issue.
CM10 was fine..I always run the screen filter app as I find even the dimmest of brightness too much. It NEVER would close this app before, since CM10.1 on using any app it does it all the time!
What is so f******* frustrating is that i am very ill in bed & with photosensitivity..so going from a screen dim of 38% to whatever the default auto is (really, any of these stock settings are bad for ur eyes long term!) just makes me scream!!!
I have 386mb or so, so obviously this is not the fault of my phone since u r having the same issue with much more memory than me it's something they have changed in CM10.1 since screen filter is a tiny app.
I frequently close all apps with a task manager & anyone that thinks they r a smart a** telling me 'android has its own memory management..u don't need to do that..it will make ur phone slower blah blah crap is talking up their exit hole lol I have disabled most apps running on various state changes via autostarts & my phone works faster for it! Some games WON'T load unless I close apps or restart - I'd like to see ur excuses for this lol There is a difference with the technical & the reality in this sense believe me!
I am considering going back to CM10 as this issue not to be sorted by now is ridiculous, but perhaps only a few have it as I don't see any replies to ur question.
I also thought about this... Where is the RAM? I tried CM10 and back to stock for 1 Day after flashing... I am more satisfied with my cleaned stock..

I feel you. I got the same problem with CM10.1. CM10.0 left me with a total of roughly 783MB. Apparently I was told it's something to do with the kernel and that the developers have not been able to work out the memory management.

You'll never get the full 1gb, because the gpu etc need some shared ram too. But I want to know why cm10.0 has more memory available than cm10.1 on the same device
Well it seems the latest nightlies (unofficial) since yesterday seem to have resolved the memory issue.

No the total usable is the same (669 MB) but there is much more of it free due to some memory leaks being fixed.
Thats nice to hear. Waiting to see if some bright mind fixes the low available memory issue on the One S. My other device the Xperia T has the same (Qualcomm snapdragon S4) chip set but much more usable memory in CM10.1(800MB)
