Hey guys,
I have a strange problem.
My test system has an Intel 14900k installed.
I wanted to use the E-Cores for unimportant VMs and the P-Cores for intensive VMs.
I have assigned the P-Cores to the same VM once and the E-Cores once. I tested both with:
Here is the result of the P-Cores:

and the result of the e-cores

How can this be? Only this one test VM is running on the host.
I repeated the tests several times
Thanks
