I have two PCs connected together, using the em card. One is FreeBSD 6
from Fri Nov  5 , the other is Windows XP. I am using the default mtu of
1500, no polling, and i get ~ 21MB/s tranfser rates via ftp. Im sure this
would be higher with jumbo frames. Both computers are AMD cpus with Via
chipsets. Perhaps its your hard drive that cant keep up?
