This was my experience as well. I discovered with Xen 2.0 using NX and
domU NFS home to another domU, that firefox cause the most drag on the
system. In general though everything was sluggish.

Moving the home dir to dom0 or native lvm device mount made that
problem go away.

The new 3.0 SMP domUs will probably be better. I haven't had time to
experience test this yet though.
