Hey there,
I'm currently testing out ESXi and I am new to this topic. Right now I have a non virtualized Windows 2016 Server (plus 2x Windows 10) that I want to virtualize. For this reason I wanted to set it up in a test environment first and see how it goes.
I installed ESXi 6.5 V3 (last supported version) on my older PRIMERGY RX1330 M1 (4 Core) and set up a fresh Windows 2016 VM and assigned 4 vCPU (max) to it.
4 Cores show up in Windows task manager.
It turns out that the performance of my VM is pretty low. I installed Cinebench to stress test and all my Cores show up on 100% in Windows. In the ESXi overwiew however I see a max utilitization of 3.1 / 12.4 GHZ. It seems like my VM is only able to use 1 core out of 4.
EXSi is still running in evaluation mode.
Any suggestions? Thank you
