My suggestion would be to try out the same setup with GENERIC kernel and the rtl driver (or even better e1000 if your Xen allows it) which is easy to do to make a simple comparison. In one of my recent benchmarks the FreeBSD Xen PV network driver performed very well in one direction, but very badly in the other. Using rtl or e1000 gave much better TCP throughput if you care equally about both directions. This benchmark was done only for internal TCP traffic between a Linux dom0 and FreeBSD dumU, the traffic never entered a real NIC. This might or might not help in your situation... -- Janne Snabb / EPIPE Communications sn...@epipe.com - http://epipe.com/ _______________________________________________ freebsd-xen@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-xen To unsubscribe, send any mail to "freebsd-xen-unsubscr...@freebsd.org"
