You're right and it is a single processor machine.  I'm not expecting
blazing performance (we far prefer reliability / predictability).
It's just really is quite slow at the moment and I'm sure that it's
down to some sort of configuration mistake.

I thought the same thing, but two processors didn't seem to solve this for me when I was running something similar with 2.0. Moving the NFS to host0 seemed to be the solution. I didn't try running the NFS server with a  dom0 kernel. That might be worth trying.
