Like you already noticed, better NICs help. BTW, which
ones do you have? See drivers' manpages for info about
hardware offloading. Also, have a look at polling(4), it
might (or might not) help.

You'll have to read ipfw(8) for that. In short, you might
have to increase the queue size so that it can hold 100ms
worth of traffic.
