Hi,
I have a question about performance vCPU for a VM.
I have an ESXi with 1 physical socket (8 cores + HT) = 16 pCPU
My VM (Windows 2008 R2) with 2 virtual sockets (x 2 cores) = 4 vCPU
Will the CPU performance of my VM be damaged ?
Not sure what you mean by "damaged" in this case. There's no such thing as damaging performance; it either is or is not within your expectations.
I would like to say "Less efficient" if I configure my VM with 2 virtual sockets on ESXi with 1 physical socket
Thank you for your response
If you have one physical socket, there's no need to set 2 sockets on your VM. Leave everything at one socket and adjust the cores. The hypervisor's scheduler will take care of the rest.
OK thanks, but for my personal information.
Do you think the VM will be "less efficient" if the VM is configure with 2 virtual sockets ?
Probably not unless you're expecting very high, low latency performance.
