3: Server Lag in Minecraft: This error can be occurred due to server lag in Minecraft. The three main components including hardware, server configuration and game-based lags that can be relating to server lag.


Improve performances of hardware components like CPU, memory and hard drive speed in order to fix the issue. Run Minecraft server on platform that allows you to monitor resource usage while server is running.

One possible way to improve CPU performance is to reduce the stress from other applications running in your computer and in system background. In Windows 10, some of most common background services that hugely impact the CPU performance are Windows update and Apple Software update. You can kill these services via Task Manager in order to fix the issue. Also, you can disable your antivirus software or if you don’t want to uninstall or disable antivirus, then enable ‘gaming-mode’ feature to enhance performances.

You can also try to improve hardware performances by increasing the RAM means increase the heap size. The trick is allocating much less memory than your total memory. So, you can try this. If you are not aware, Minecraft game saves your progress after every 45 seconds. If Minecraft server is causing server lag, then it might possible that some background process or backing system running in background consider excluding files containing Minecraft world files. You can also opt for an SSD or RAMDISK instead of using Hard drive in order to speed up hard drive speed.

Server Configuration:

You can check and change server configuration in order to fix server lag in Minecraft server. You should make sure you are running Server JRE which is not available with regular Java or Server jar installation. Ensure when you execute Minecraft server instance with this runtime environment JRE.

When executing Java arguments, you need to ensure they are supported by your installed Java version. For example, if you are running Java 8, you would use the argument below.

-server -Xms512M -Xmx2048M -XX:+UseG1GC nogui

  • -Xms512M -Xmx2048M: This argument sets the minimum memory (RAM) as 512MB and maximum memory as 2GB
  • -XX:+UseG1GC: To minimize any delays when working with large heap sizes, we use this argument to set the garbage collector as garbage first collection.
  • -server: This enhances performances by ensuring the Minecraft server is running the server virtual machine
  • nogui: The Graphical User Interface is known to take a good share of system resources. That is the same for the GUI console launched when you start the Minecraft server. The nogui parameter enables you to run a headless server, thus improving overall system performance.

Game-based lags in Minecraft server:

This issue can also be occurred due to issue with game itself. In such case, you can follow some tips that you can try next time to avoid server lagging.

  • You should avoid repeating blocks that store their recent output that can tend to cause more lag compared to blocks that doesn’t store their output
  • Don’t use too many unnecessary flashing lamps. Lighting updates can be quite laggy
  • AI entities are one of laggiest entities in the game. You can use F3 to see the total number of entities in the area.
  • You should avoid using entities having the same UUIDs, You can easily kill these UUIDs with following syntax

/kill  < UUID>


/kill 7686887tgj-fgfg-45gb-a345-6578786gbc

  • You should keep the number of players on the server in check because too many players might cause serer lag
  • Lower Spawn limit of Monsters
  • Remove Additional plugins
