FWIW, this is how my igb(4) system is tuned and with PF, it's able to fill 4xigb interfaces: /boot/loader.conf: # 16 CPUs net.isr.maxthreads="8" net.isr.defaultqlimit="4096" net.isr.maxqlimit="81920" net.isr.direct="1" net.isr.direct_force="1" net.isr.bindthreads="0" kern.ipc.nmbclusters="262144" hw.igb.max_interrupt_rate="32000" hw.igb.rx_process_limit="500" hw.igb.header_split="1" #This setting doesn't seem to work hw.igb.txd="4096" hw.igb.rxd="4096" /etc/sysctl.conf: net.inet.ip.fastforwarding=1 kern.random.sys.harvest.interrupt=0 kern.random.sys.harvest.ethernet=0 kern.random.sys.harvest.point_to_point=0 Ian -- Ian Freislich _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
