I mostly use PaperMC, so there might be traces of that in the code.
Should work for any version of Minecraft, report to the issues page otherwise.
A plugin for small servers (eg. with friends) that lets the server sleep / hibernate when no players are connected. It saves on computer resources.
- CPU load is greatly reduced, from ~20% it will be about ~1% (x20 reduction) when there are zero players online. RAM is also reduced somewhat.
- There is a default config, but almost every single feature can be changed in the config. Use the config to configure the plugins sleep/nap time, startup time, delays, etc... feel free to experiment on your server.
- Feel free to check out the code as well for explanations/comments.
For small servers I use java -Xms256m -Xmx3G -jar <jar file> nogui to reduce inital RAM usage.
However, for performace reasons you might want to use the RAM as much as possible, then use google and look up "aikars flags java".
