I've tried without fast forwarding, I've tried without the TCP sendspace as well as reducing it to 65K, I let maxusers auto tune itself and I've even tried uping the KVA space. I'm at a loss, what would be the ideal sysctl's/loader.conf for a router thats doing a fair amount of traffic? _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[EMAIL PROTECTED]"
