Does OpenBSD/newer PF have better throughput on 10Gbe+ hardware? I've heard that OpenBSD/PF tends to run into issues due to giant lock and SMP issues.

Since you seem knowledgeable, any pointers to information about that?

everything I've seen indicates OpenBSD pf wins on slower single cores but on fast multi core hardware FreeBSD pf wins.
