IIRC vmware doesn't allow people to publish benchmark results like that.

Anyway, taking a quick glance, the benchmark was using SQL 2005 (which
implies windows), but searching for the words "pv", "para", or
"driver" returns no result. So it's only normal that xen performs
terrible on that benchmark.
