I use Proxmox extensively in my homelab where I have virtual machines for many of my clients (I'm a freelance Postgres DBA and need to keep development / scratch machines separate).
It would be nice to be able to grow and shrink resource usage even more and it got me wondering about hotplug memory and CPU. I discovered that NUMA needs to be enabled in order for this to work. The help indicates that performance can actually improve with NUMA enabled, but I wonder, are their any downsides? If there are none, why isn't it enabled by default?
