This plugin is mainly focused for memory usage optimization for those with memory problem.

Note: This plugin is designed to optimize your server’s memory usage. Its effectiveness may vary depending on the number and nature of other installed plugins. While it is safe to use and does not interfere with server files or world data, if you are unsure or running in a production environment, it’s recommended to create a backup before starting the server with this plugin enabled.

(It is recommended to stop the server and start it once again if starting the server with the plugin for the first time)

Caution: Do not rename the plugin because renaming the plugin will make it unusable in the server, causing error in the plugin, it's better to use it by its original name.

Use /optimizer help to list all commands. From the MasterOptimizer-1.5.0 the command are changed to /mo help m=Master, o=Optimizer.

Commands are removed from MasterOptimizer-1.3.0 and MasterOptimizer-1.4.0.
