Hi,
More to come, and if you can think of other tests let me
know. Next is VLAN performance.

Not sure, but I would unload iptables from the kernel when
testing. I will check again today as I want to go back and test the
LINUX kernel in UP mode to see what difference it makes.

As just a router, they seem fairly close without any firewall
rules. RELENG_4 seems to be the only clear leader in terms of raw
pps, at least in these tests. I am still puzzled by the fact that
ipfw does relatively poorly compared to RELENG_4.
I also have some PCIe bge nics I will try and test. There are some
patches that Bruce Evans posted and I would like to see how they perform.
