my experience with netmap is that my re cards on PCIe bus can do over 1Mpps in receive (don't rember the exact number), but only about 400-450Kpps in tx. At least on the tx path i got approximately the same speed with the netsend program (in tools/tools/netrate/netsend). cheers luigi _______________________________________________ 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"
