Minecraft plugin to save electricity and performance

Hibernator

What is it?

Hibernator is a minecraft plugin inspired by Hibernate that will hibernate the server when no players are playing on it

How does it work?

In hibernation, the plugin will lower the server TPS (ticks per second). You can think of it as the plugin creating "fake lag". Hibernation will automatically turn off when a player joins. When all players disconnect, hibernation is enabled again.

Usage

Turn on Hibernator

/hb enable

Turn off Hibernator

/hb disable

Check Hibernator status

/hb status

Reload Hibernator

/hb reload

What are the disadvantages?

• Because the server is frozen during hibernation, plugins that run tasks even when players are offline will not work correctly!
e.g. Dynmap won't be able to run its web server during hibernation.
• Your console will be spammed with "Can't keep up! Is the server overloaded?" messages. This can be resolved by changing the warn-on-overload setting to false in bukkit.yml, but note that this will disable all server overload warning messages.

What are the benefits?

• In hibernation CPU usage is reduced to 0-1%
• Saves electricity

hibernator's Issues

Schedule time is invalid

The real schedule time does not match the time specified in the config. Usually the queue starts the game ~20 seconds before the actual time specified. This has probably something to do with BukkitScheduler.
