Customizing your Minecraft server with Java flags can significantly enhance its performance and efficiency. In this tutorial, we'll guide you through the straightforward process of creating and configuring your own user_jvm_args.txt file. Unlock the full potential of your server by learning how to tailor Java settings to your specific needs!
You can customize the behavior of your Minecraft server by adding your own Java flags. This allows advanced users to optimize performance based on their specific needs.
Step 1: Create the user_jvm_args.txt File
Connect to your server via FTP (e.g., WinSCP or use the WebFTP).
Navigate to the root directory of your server (where server.jar is located).
Create a new file named:user_jvm_args.txt
Step 2: Add Your Custom Java Flags
You can write the flags in one of two ways:
All flags on a single line, separated by spaces:
-XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:+UnlockExperimentalVMOptions
One flag per line:
-XX:+UseG1GC
-XX:+ParallelRefProcEnabled
-XX:+UnlockExperimentalVMOptions
Both formats are supported; choose whichever is easiest for you to manage.
/!\ Notice, You must only adds flags in this file. You do need to configure XMX or XMS values according of the memory allocated by your plan. Do not configure any .jar file; it's determined on the panel.
