Check the milliseconds per tick in every world on your server with a single command. This can help you check which world is lagging your server and barely uses any resources at all.

I did not test this plugin on any other version than 1.20, so it will probably not work on other versions, but you can try.

Commands:
/msptperworld (lists all the worlds on your server and their mspt)

Permissions:
msptperworld.command (permission to use the /msptperworld command)

This plugin was specifically made for the Minecraft Hosting Platform 'WorldHost', if you are having problems while using this plugin, contact me on the WorldHost Discord Server: https://discord.gg/mwdKBAEpJb
