What is your throughput with native/non-xen kernel? It should be
similar, and if that's the case then the problem lies in your general
networking setup.

I can saturate 1 Gbps link easily when transfering data from dom0/domU
to external host. I'm using x86_64 btw, so probably your problem is
Itanium-specifc.
