So, as a point of comparison, Postgres should take a 20-30% hit in performance from running under KVM-QEMU or Virtualbox. It's almost 50% under Xen. This is obviously looking worse than that.

The part I don't know how to compare is how transactions per second translates to the test suite as I assume there isn't 3000 simultaneous transactions while running the tests.
