Still can not see any objection for not using fastforwarding, and usually ipfw ruleset can be rearranged for using dummynet & netgraph with one_pass=1. Could you show your 'ipfw show' output? (hide ip addresses if you wish but keep counters please).

It depends on traffic pattern, try to increase it and watch search_steps/searches ratio (~1.001 is good enough) -- Oleg. ================================================================ === Oleg Bulyzhin -- OBUL-RIPN -- OBUL-RIPE -- o...@rinet.ru === ================================================================ _______________________________________________ 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"
