Hi Paul

Is this worth looking into? Apparently it speeds up memory cards. Maybe worth putting in future roms?

I just editted the file mentioned in the XDA thread from 128 to 2048 and 3072 i got 11/18 MB at 128 setting and 15/30 at 3072. The speed increase on the internal memory is very noticable. Pictures load way quicker then before

Ah thought you could change it in CWM but that changed after the last beta :D i'll test it with fix permissions but dont know if that will help.

Ok it works like a charm. You cant do it anymore from CWM directly, but if this will be built into the rom directly it would be sweet indeed :D went from 14//20 to 20/40

I've tested 3072 and 2048, on the moment i'm using 2048, but i think it also depends on what kind of sd card you are using, a class 2 card will never go as fast as a 6 or 10.

True but i think that SD tools tests the internal storage as it mentions 5.51 gb as total space and i got a 16gb sdcard :D so we all should get about the same performance if nothing in the background is accessing the internal storage.

Correct indeed, SD tools gives some information about the SD used. i'll look tommorow and post the info in here B)

Looking forward to it.

Just curious: won't it be much overhead with small files though? And worse performance if performing file operations for multiple small/tiny files at the same time?

i strongly believe so, and i have undone the changes. installing apps from the market really takes a hit in speed and also recovery with titanium seems to take about 5x as long (yes, really)! best to undo these changes on fr10 with the free app sd increase from the market and set it back to 128.
