Performance

When Ollama, Minecraft, and etcd compete for CPU on the same host, the scheduler doesn't know which one is critical. Proxmox cpu.units gives etcd 2x priority — and without it, leader-election timeouts cascade into cluster instability.

All VMs and LXCs starting simultaneously spiked the Proxmox host load to 147. The fix was NFS first, k3s nodes 30 seconds apart, and LXCs last — a boot order strategy that costs nothing but prevents boot storms.
