FBSD 1GBit router?

What kind of network cards are you using, and what bus type are they using?

>From my experience, I was never able to get over ~300Mbps routing from
one PCI-X NIC to another PCI-X NIC.  I switched out the bus to a
PCI-Express and put a couple of Intel PCI-E 4x gigabit cards in and I
was able to get over 950Mbps throughput.   Sorry I don't have my
sysctl.conf settings, that box was reallocated after we replaced it
with some Cisco junk.
