I saw a similar problem yesterday: I downloaded a new software for our 3Com
switch and experimented with full duplex mode with my DE450 / DEC21041 cards.
The full duplex setup didn't work properly, and I switched back to half
duplex (on the switch and the card of course) and tested the performance with
a second PC (directly connected to the switch): short after reboot I got a
large file via ftp; the performance was ok (~950kB/s) but the collision
count was *higher* than the TX count (>100% ;-)!
I thought this may happen because the other machine transmit (data) packets
very fast and my transmitter isn't able to get the wire for the ACKs?
Is it possible to saturate a 10BaseT/half duplex wire with one ftp transfer?
Can someone with deeper network knowledge comment on this?
