If you don't handle RTP, I'm sure it is amazing. However, if you have to do
voicemail, stream audio from the server or do any kind of actual
time/latency/jitter sensitive processing, I don't care how much you tune
your hypervisor, it's never going to scale.

I've not seen this behavior on Vmware ESX 3.5u2. Maybe an issue on Vmware
Server or Workstation?
