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. -M
