I've had similar problems with 3com 3c509 NICs. In certain configurations they seem to either drop packets or just somehow manage to be terribly slow. The ep driver used to be described as "slow/buggy" in the kernel config files, so I usually try to stay away from them on FreeBSD systems. If you have any other non 3c509 NICs handy, I'd recommend you try swapping them.
