Let me disagree :) I'm experimenting with bridge and Intel 82571EB Gigabit Ethernet Controller. On quad core system I have no problems with the stability of the bridge without polling. taskq em0 takes 100% CPU, but I have another three (cpus/cores) that are free and the router is very very stable, no lag on other interfaces and the average load is not very high too. > > Kind regards, > Ingo Flaschberger > > _______________________________________________ > freebsd-net@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" -- Best Wishes, Stefan Lambrev ICQ# 24134177
