Intel turbo boost on VM?

Hi all,

Currently we are testing regarding CPU performance on a VM vs. physical host. We’ve noticed that on a VM our software used for testing is 10% slower then on a physical host. Then we noticed that on a VM the core frequency is set at the base frequency of
our Intel processors (in task manager, but also in other tools for checking CPU frequency). On the physical host the frequency is higher because of the Intel turbo boost being applied. 

We’ve also tested disabling the turbo boost on the physical host. Then the difference in CPU performance between the VM and the physical host is only 3%. 

Is it as designed that intel turbo boost isn’t working on a VM? Or how can we pass the intel turbo boost onto the VM so that it is also being applied there? 

Kind Regards,
Joël
