I'm pretty sure your problem is different. My point in this thread was
that domU <-> domU network performance works great if you use
2.6.18-xen dom0 kernel. Grant was having problem with a similar setup
due to broken pipe, so I suggested to disable iptables first.

Your low throughput was on pv_ops dom0 kernel, right? AFAIK there's no
solution for that (yet).
