And did you install Xen PV-on-HVM drivers? Without those the performance will 
be bad.
RHEL5 has those drivers available.

Also when you're using a Linux guest why not install it as PV? Then you don't
need any additional drivers and the performance is good out-of-the-box? 

RHEL5 supports running (and installing) as a Xen PV guest.
