Tuning Practices for VM CPUs

Although a CPU is one of the core resources for correctly sizing and managing virtual machine performance, it is also the one with the fewest number of moving parts when it comes to tuning. Essentially, you can affect the number of vCPUs that you allocate to a virtual machine and you have some ability to control how those vCPUs are seen by the virtual machine. Aside from that, there are few factors on the physical server that are changeable that can effect on how well the virtual machines perform.

Choosing Multiple vCPUs vs. a Single vCPU

When you’re building a virtual machine, one of your initial configuration choices is the number of virtual CPUs that will be allocated to the VM. The choice would seem to be fairly ...
