Hi all, i m investigating about the huge lags when playstore update somethings, or while typing in keyboard, and for me this is related to slow I\O performance. I ve done some benchs, with Androbench wich measures the overall speed of the Mmc.

I did all the tests with:
Carbon rom by Moonlight
all I\O sheduler
2048 read ahead size
Interactive governor
384/1.7Ghz default
Normal use condition
PmR tweaks (attached)
Dalvik runtime
There are some screens:

CFQ:

ROW:

NOOP:

DEADLINE:

The strange thing, is that (in this rom) the best i\o is Cfq. As i know it would be the worse.
Btw, i resolved all the lags (expecially while typing) by flashing some i\o \ ext4 \ sheduler tweaks with Pimp my Rom app. This is what i had before the tweaks, with row I\O sheluder:

ROW BEFORE PMR TWEAKS:

NEXUS 4 TESTS (not done by me tx to usotech.com)

Basing to this tests, we have very low write speed.. meh..

Please, feel free to upload some benchmarks, im very curious about I\O speed in M1cha' s roms and stock Miui!
Please also dont goo too much ot, keep the trhead clean!
Sorry for my bad english

Ps: in the attachments the scripts that i have applied, unzip, put in system\bin\init.d and set permission to:

hahahaha. no clue how that happened :D androbench does not seem to work as it should. Everytime I bench, I have huge differences without changing anything
