Use FreeBSD 7.0 if you want new PF and a higher-performing network
stack. 7 has lots of networking improvements over FreeBSD 6.
I have no idea about OpenBSD 4.2/PF against FreeBSD 7/PF. Both
releases have made substantial gains.
It actually seems to me that you're in an ideal position to create
those comparison benchmarks. One hosts with each OS, using CARP to
failover between them. I suspect that both groups of developers would
be interested in the results. Once you have made a decision,
upgrading one is simpler than changing both.
(I used to have a PF cluster with this configuration, a couple years
ago. It worked just fine, and when I suspect OS-related bugs I would
swap from one to the other. In every case my suspected bug turned out
to be operator error but wow, did I learn a lot about TCP/IP and
traffic shaping. :-)
