I dont see any problems with cpu performance. Minecraft is basically onethread thing. Jellyfin works on intel hardware acceleration. Everything works on lxc or docker. No vms running all-time

“Big HP” : intel i5 6500, 32gb ram, 3xssd512gb(one raid 1 for proxmox and containers/vms and one ssd as file server/samba server)

Proxmox lxc containers:nextcloud, pihole, file server, jellyfin, docker(portainer, heimdal, qbit, watchtower, pyload), minecraft spigot
