I recently did some tests, 'completely unscientific', just real
world experience. 2 similar servers, Intel Core 2 Duo 2.1Ghz 4MB
cache, 4Gb RAM, 2 Sata2 320GB, and I emphasize similar not
identical. It was mostly for a database server, for Firefird and
IBM DB2.

VMware server was somewhat faster in the disk access, and Xen was
somewhat faster as a 'RAM server'. Overall, they were both similar
in speed, we chose VMware because drive access was faster.
