Ayo folks , i tried to tweak a bit some kernel options and discovered that our device LOVES low readaheads .
So i pushed the internal memory readahead to 96kb (under this there is no improvement) with kernel toolbox and there : magic , the device gets snappier , benchs get significant improvement but overall performance explodes: latency got from 70ms (stock no modification) to 29MS!!
You can try yourself :
Scheduler : ROW
Internal card readahead : 96 or 64kb
Entropy read: 128
Entropy write : 1024
