It's mostly CPU bound and this is 'virtualization' not 'emulation' and the instructions are executed unchanged on the physical processor. IOs would need some intervention by the hypervisor and that could make a difference. 

  But my emulator is providing Alpha hardware emulation (per the "DS10" line in my VUPS output). What I'm interested in seeing is how VMS x86-64 performs on this Dell server, compared to the additional overhead of providing a complete emulated DS10.
