LagFixer Plugin (1.20.4, 1.19.4) is a meticulously developed tool designed to combat lag issues that can hinder gameplay on Minecraft servers. It targets common factors contributing to lag, such as excessive entity presence, inefficient chunks, and resource-intensive activities. The plugin’s primary goal is to create a more responsive and fluid gaming experience for all participants on the server.


  • Creature Movement Optimization: LagFixer optimizes the movement of creatures and mobs on your server, reducing unnecessary strain on server resources and minimizing lag caused by large herds or hordes.
  • Redstone Clock Prevention: Say goodbye to lag-inducing redstone clocks! LagFixer intelligently handles redstone mechanisms, preventing them from causing excessive lag on your server.
  • Server Lag Monitoring: LagFixer monitors server lag and takes proactive measures to reduce it. It automatically disables the most resource-intensive options when the server is under heavy load.
  • Console Logging Filters: Keep your server console clutter-free with LagFixer’s logging filters. Disable error pop-ups and unnecessary messages for a cleaner console interface.
  • Mega Animal Farms: LagFixer’s creature movement optimization opens up new possibilities for expansive animal farms. Players can now create and maintain larger farms without sacrificing server performance.
  • Creature and Item Stacking: LagFixer offers entity and item stacking options, allowing you to combine multiple entities or items of the same type into one with a designated quantity, reducing entity count and saving server resources.
  • Chunk-based Entity Limits: Control the number of entities per chunk with LagFixer’s chunk-based entity limit feature. Prevent overcrowding and potential lag spikes caused by excessive entities in a single chunk.
  • Minecart Cleanup: LagFixer automatically detects and removes unnecessary minecarts with chests that might clog up server memory, optimizing performance and ensuring smoother gameplay.


LagFixer Plugin offers command and permission options for server administrators:

  • /lagfixer reload: This command allows administrators to reload the plugin’s configuration without requiring a server restart.


  • lagfixer.admin: This permission allows players or administrators to access and utilize the plugin’s admin-related features.

How to install:

  • Download a plugin of your choice.
  • Place the .jar and any other files in your plugin’s directory.
  • Run the server and wait for it to fully load.
  • Type stop in your Minecraft server console to bring the server to a clean stop.
  • Run the server.
  • All done! Your plugin should be installed and ready to be used.
