That sounds like you have problems with some network offloading
settings.

Have you tried for example this in the domU:
ethtool -K eth0 tx off
After doing this throughput increases between external node<-> guest, it becomes 940Mb/s on 1G card in both directions. But my domU<->domU throughput just reaches 300Mb/s. It should be in Gbits/s since loop-back is used in this case. How can i improve it to Gb/s
Does that help? If it doesn't, try playing with the other offloading
settings.. you can check them with "ethtool -k eth0".
Yes it helps also other offloading parameters.

Do you have errors in the dom0 dmesg? No

The INTERNET now has a personality. YOURS! See your Yahoo! Homepage.
