I just upgraded both my xen machines to the latest (yesterdays hg pull)
and both appear to be doing the same thing now. One of them is SMP
though, so the problem is less apparent, but if do a 'cpuburnP6' on
dom0, the domU's slow down to a crawl.

The problem really does appear to be scheduling related, not network, so
I haven't adjusted the network bridge configuration yet, but will do so
if you tell me it's worth a go.

Thanks

James
