Which version of FreeBSD and how much traffic/pps?

I believe that there has been significant improvements to the networking
stack in recent versions of FreeBSD, plus there are also a lot of sysctl
tunables which can significantly improve networking performance. I have
a hard time believing that the networking performance of recent versions
of FreeBSD would not be competitive in comparison to other unixes.
