Subject: usbdevfs comparison
Hi everyone. Just performed a comparison by dumping Sting's Mercury
Falling CD to the Rio. Here's the results (using uhci.o with unlink
optimzations turned on) I seem to remember a uhci driver that was MUCH
faster at one time. Looks like usb-uhci is a bit faster and the usbdevfs
vs. kernel space very comparable
===========================================================
With uhci.o (with unlink optimizations turned on)
USBDEVFS Kernel Space Driver
End Time 14:28:57 End Time 14:46:34
Start Time 14:15:07 Start Time 14:32:32
--------- --------
Time used 13:50 Time used 14:02
===========================================================
Now, with usb-uhci.o
USBDEVFS Kernel Space Driver
End Time 14:57:03 End Time 14:52:12
Start Time 14:54:50 Start Time 14:49:00
-------- --------
Time used 2:13 Time used 3:12
