Are you using LVM-backed domUs?
High numbers like this give me hope that my problems are not inherent in Xen.

I guess "hdparm -t" is not very significative, but anyways:
dom0: hdparm -t: 149.17 MB/sec
domU: hdparm -t: 97..07 MB/sec
However, real performance is somewhat lower, at about 70MB/s for dom0
and about 33MB/s
