I remeber there being some sort of issue with large number of interfaces, however I think it was trivial to fix and may have already been. Sorry if this isn't so helpful, but I can't remeber anyone recently popping up and complaining about the perf with lotsa NICs in machine. -- -Alfred Perlstein - [alfred@freebsd.org] Daemon News Magazine in your snail-mail! http://magazine.daemonnews.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
