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:

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:

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
