ICMP is not a good way to perform such tests as many have mentioned, better use iperf. We have a FreeBSD 6.2 / pf box handling 2Gbps of traffic, real traffic, it will probably handle more, we just had no capacities or need to test. Hardware is a Single 2.4 Ghz Xeon with 2 x Intel Quad Pro 1000MT PCI-X Controllers on separate PCI-X Busses. Here are most optimal options: Kernel: ------------------------------------ options DEVICE_POLLING options HZ=2000 Sysctl: ------------------------------------ kern.polling.idle_poll=1 kern.polling.user_frac=20 net.inet.ip.fastforwarding=1 net.inet.ip.intr_queue_maxlen=5000 kern.ipc.maxsockbuf=8388608 net.inet.tcp.sendspace=3217968 net.inet.tcp.recvspace=3217968 net.inet.tcp.rfc1323=1 Regards Kirill _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[EMAIL PROTECTED]"
