Hello, I''ve done a couple of test with different amounts of vCPUs checking how the VMs influence each other depending on the amount of vCPUs. Tests I have done checked with different weight, different amounts of vCPUs and different number of threads on the client system. I figured out that you have a big advantage in using more vCPUs if your clients runs a lot of threads (therefore other VMs slowdown). That can be even more important than the weight of the VM. Is that an expected behaviour? I found no case in which it is a disadvantage to have a lot of vCPUs. So is there any reason not to give every VM 4 or more vCPUs? Do you have an idea of special cases to check where a bigger amount of vCPUs might be a disadvantage?
