The performance we are getting is around 500%-600% faster than Xen based BSD virtual machines
I don't know where you're getting your numbers from, but Xen doesn't have a 5x performance penalty. I'd believe you if you said that QEMU or Bochs had a 5x performance penalty, but Xen is more along the lines of 5%. (Of course, if you run an instance and give it a small fraction of a CPU, you get what you pay for.)

I'll go ahead and publish the benches shortly.
