Up to 30 MHz on one VM

[remzy]

Hello.

I have a four-processor server is a four core. I ESX server is 3.5. Core 2.4 GHz. So cpu total more than 38 gigahertz. Installed WINDOWS 2003x64 and issued 4 processor. When masimalnoy load server uses slightly more than 4 gigahertz 4x2.4 ~ 9. How to get the most performance for virtulnoy machines in a single server. Should not the number of processors, and performance. At up to 30 gigahertz to a virtual machine.

A virtual CPU (vCPU) will only be able to run as fast as a single physical CPU core. So with just a single 4 vCPU VM on the host, you'll only use the processing power of 4 CPU cores. ESX is not able to combine physical cores to create super vCPUs.

So not to get more productivity 9 gigahertz per virtual machine?

no, you can not get any more umph out of a vCPU as Dave states ESX does not combine pCPU cores to make a super vCPU monster it is a one to one mapping therefore a vCPU equals a pCPU core. So in your case vCPU equals 2.4Ghz, a 4way Guest is still rated at 2.4 Ghz it just has for processors just like a physical machine.
