Sockets and vCPUs

[kernelroute]

Hello,

I'm currently doing some contract work and looking over some Proxmox configurations to help improve the performance of several servers.

I've proceeded to enable multi-queue across the 8 CPUs on one of the servers, which has helped balance traffic more efficiently, although, I am a bit confused as to why the configuration I've inherited is configured to use 4 sockets, and 2 cores when the physical server only has 2 sockets?

I'm going to look at changing to 2 sockets, 4 cores, and enabling NUMA, although, I'm genuinely wondering if this configuration results in a performance hit.

Any input would be appreciated.

Thanks!

All my servers are 2 socket, I enable numa and match the physical number of sockets in the VM config.
