With both the sata drive (sda) and flash drive (sdb) (both usb)
connected, and network (also usb) up and running, I did some raw read
tests:
dd if=/dev/sda1 of=/dev/null bs=4096 count=102400
dd if=/dev/sdb1 of=/dev/null bs=4096 count=102400

I have not, but given that performance is increased by *any* other usb
activity (storage, mouse, ttyUSB0), I doubt the ethernet driver itself
is at fault.
