If anyone has tuning advice for FreeBSD 5.3, I'd like to hear it.

Three things:

 sysctl net.inet.ip.fastforwarding=1

 Don't use SMP for packet forwarding.  It doesn't help anything and
 introduces only locking overhead.

 Upgrade to the latest RELENG_5, there are a couple of fixes for things
 that may hurt you here.  Especially there is a fix for the transmit
 queues on the em() driver.
