Try setting sysctl net.inet.tcp.delayed_ack to '0'. If that helps noticably you may tune sysctl net.inet.tcp.delacktime to a lower value than the default ('100' ??). delacktime is only in effect when net.inet.tcp.delayed_ack = '1'. Does that help any? -- Sten Daniel Sørsdal _______________________________________________ freebsd-performance@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-performance To unsubscribe, send any mail to "[EMAIL PROTECTED]"
