If you go higher than 100Mb/s speeds, look for zero-copy boards, especially
on the Gigabit side that FreeBSD supports. You have drastically low
interrupt overhead and your speeds to move packets around increase. In my
experience, its not the CPU that gets bogged down (first) but the interrupt
load on a properly configured (software) box.
