This only applies to people competent enough to compile their own builds, and who own a PP based target (Sansa / iRiver H10 / iPod)I've just started this new page in the wiki :
UsbPerformance in order for people to measure the sort of performance they can get with the new Rockbox USB code, and compare it with the speed available from the Original Firmware on their DAPs.
I'd love to see a few more contributions here, and I'm sure gevaerts would too.
