That said, if performance is critical, virtualization is clearly not the best option here. ESX (i) is what is called a "type 1 hypervisor": a dedicated virtualization operating system running directly on the host hardware, with full access and control to hardware resources Player/Workstation/Server are "type 2 hypervisors": they are applications running on an underlying operating system (Windows or Linux) they have to go through it to access hardware, and this is the main reason ESX (i) is definitely better the difference in performances is simply astounding.
