I see the same behaviour with ng_nat and ng_ipfw. 7-S as of Nov 2009 on Xeon E5410 (4 cores). 16 ng_nat nodes connected to ng_ipfw. Sometimes one ng_queue eats 100% of one core while other 3 ng_queues sit idle. I'm going to set queueing on all ng_nat's hooks to see if it will help. -- Eugene Perevyazko _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
