Assigning more vCPU’s to a VM may not necessarily increase CPU performance of a VM. Here are some best practice recommendations.
- Start with one vCPU per VM and increase as needed.
- Do not assign more vCPUs than needed to a VM as this can unnecessarily limit resource availability for other VMs and increase CPU Ready wait time.
- Performance degradation may occur on multiprocessor VMs in which the number of vCPUs was greater than the number of vCPUs in a NUMA node. Generally, try to keep multiprocessor VMs sized so that they fit within a NUMA node. In PvDC this would be (1, 2, 4, 6, and up o 8vCPU).
