I don't know what he means but he states, and I quote: 
"We'll test a java web application (online banking), and we basically
want to see which environment will process more TPS
(transactions per
second), which is directly related to disk I/O."

To me he's benchmarking native RHEL5 against virtualized RHEL5, same way one could benchmark RHEL5 against Ubuntu or Solaris.  Maybe he will tell us what he meant by that and to be honest, I might understand him incorrectly because of my english.

I would suspect that OP is trying to asses whether the performance hit
would be significant enough to outweigh the benefits of virtualization.
