What Does This Mod Do?

This mod helps reduce server lag caused by excessive entities on your Minecraft Forge server. It includes an automated clear-lag system that periodically removes loaded entities to improve server performance and stability.

The mod also supports configurable warnings, automatic cleanup intervals, and a customizable entity blacklist to prevent important entities from being removed.

Commands

The mod currently includes 4 commands:

/killall
Instantly removes all loaded entities across the server, excluding any entities added to the blacklist.
/lr-blacklist-add [entity]
Adds a specified entity to the blacklist so it will not be removed during cleanup.
/lr-blacklist-remove [entity]
Removes a specified entity from the blacklist.
/lr-config-reload
Reloads the mod configuration and blacklist files without requiring a server restart.

Configuration Files

The mod configuration files are located in:

config/Lag Removal/

Inside this folder you will find:

config.json — Main configuration file

Using this file, you can:

Change the delay between automatic cleanup executions
Enable or disable warning messages before cleanup
Prevent named entities from being removed, even if they are not blacklisted

Supported Minecraft Version

This version is currently built for:

Minecraft Fabric 1.20.1

Does Every Player Need the Mod Installed?

No. This is a server-side only mod.

Only the server needs to have the mod installed for it to function. Players can join normally without installing anything client-side.

The mod can technically run in singleplayer, but it is primarily designed for multiplayer server environments.

Installation

Download the mod .jar file
Place it into your server’s mods folder
Start or restart the server

The mod will automatically generate its configuration files on first launch.
