Are you using amd64 or i386 kernel ? the config implies you are using
i386
HZ and Pooling values in those config files have been changed by me during
test several times as you will see in results table.
The kernels have pf compiled in but it is not turned on at this time.
The network topo is: http://www.codeangels.com/misc/fwtest/first/topo.gif
And here are the results:

* Any other ideas on improving performance of this box?
I found
kern.polling.idle_poll=1
to improve performance in polling. Also, try updating the box to 6.2
first as there are quite a few improvements to the em driver
You can also fiddle with assigning less to userspace with
kern.polling.user_frac=30
Don remember for sure, but ipfw seemed to be a bit faster that pf.
Also with no firewall loaded there seemed to be quite a bit more
throughput... However, that kind of defeats the purpose of a firewall.
Also, did you try without polling in the kernel ? The way the updated
em driver works should negate the need for kernel polling as well.
Also if you dont use INET6 or ipsec, I would remove them from the
kernel
