Minecraft servers are resource hogs even when idle. Enable the built-in idle server shutdown (IDLE_SERVER=true). It automatically stops the server after a few minutes with no players and starts it again when needed. It's not enabled by default.

I'm struggling to find documentation on `IDLE_SERVER`, do you know of any? The only place I see it documented is on ArchWiki [0], but I don't know if that is an Arch distribution specific feature. I do see `pause-when-empty-seconds` [1] when looking at the wiki, which seems the closest, although I can't find doc on what "paused" means (this is the closest [2]). Looks like a fairly new feature (2024), but it's neat they've thought about it.

    Based on my read of the `minecraft-server` package [0], I think it is using a management script wrapper around the raw Minecraft JAR [1], which implements the aforementioned idle functionality [2].

  You might be right: I am indeed using https://aur.archlinux.org/packages/minecraft-server https://aur.archlinux.org/packages/minecraft-server. I thought IDLE_SERVER was an upstream feature but it seems to part of that package's management script.
