Re: Optimal number of CPU cores for maximizing guest performance

Thanks for your response, Scott...

 

I think what's confusing me is that I'm not quite sure what the guest OS sees and how it can use that...

The CPU has 6 actual cores and due hyperthreading, MacOS is showing them as 12 "virtual" Cores.

In the VM settings, are we configuring the number of physical or virtual cores that the VM gets to use? I suppose its the number of Virtual CPUs. The fact that the 12 vCPUs exposed by the i7 chip are actually running on 6 physical cores is probably not exposed to any part of the stack at all so it doesn't actually matter, right?

 

I also don't yet follow why the what you are saying would be the reason for the warning. Could you elaborate? The warning is saying that assigning more than half of the Cores to the VM might slow down both the guest and the host and I dont understand how that can be the case...

 

Cheers,

Lars
