EmptyOptimizer

This plugins allows you to change the Minecraft tickrate and optimize the memory usage when there's nobody connected to your server instance.

This may be useful in these scenarios:

Lobby servers
Minigame arena servers
Reselled hosted servers which aren't running a Survival world
PVP servers who need to run over 20 TPS (Not recommended)

This plugin will save a lot of resources if you have lots of tiny servers which are usually empty.

NOTE: Please be advised that this plugin will prevent entity ticking (movement, etc.), liquid flow, tree growth... and can have unintended Minecraft vanilla features in a Survival server.

Config file:

Code (Text):

emptyTps: 0.1 # 1/10 of a tick (995 ms per run)
startup: true # If you want the empty TPS in the first server startup
unloadSpawnchunks: true # If you want to keep the spawnchunks loaded when the server is empty

The empty TPS must be between 0 (not included) and 20 (not included). When the server has people, it will try to run at 20 TPS, and when everybody disconnects, it will run at 1 TPS.

Planned features:

Compress entity data
Try to minimize the memory usage while nobody's in.
