I have not had the opportunity to test, but it sounds like expected behavior due how I/O is handled within Xen. It's a know fact that disc I/O is slow so I would expect the same for network I/O.

Hi all, I have problem reaching 1Gbps network speed with dom0 / domU (paravirtualized) on my centos5 installations.

The fastest speed I measured in domU was about 800/600 receive/transmit Mbps, dom0 being a bit slower. I'm using bridging (eeither with default xen/centos network-bridge script or with my own scripts assigning vlans to bridges).

Is anyone experiencing same network slowdown? Or could it be just some configuration issue on my side?

Thanks,
