To be honest I’m not sure if this is the right place either. I doubt MineOS actually handles the allocated resources to the server, except maybe ram. As well as that, you can actually run more MC servers than cores (eg 5 Minecraft servers on a 4 core system). Even more, spigot and it forks are also multithreaded so yeah. If you want a faster reply, I recommend using spigot forums for a question like this and formatting it something along these lines: Does spigot/the minecraft server use one core per instance?
Anyway, hoped this helped and if I’m wrong anyone don’t hesitate to correct me!
