[CentOS-virt] xen dom0/domU network speed

[David Kostal]

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,
