How Much Ram Should Feed the Beast Be Using

Minecraft: Java Edition servers consume a lot of PC resources, especially RAM. If your Minecraft server uses up all available RAM, players will start experiencing lag and other network issues. To avoid this, you should carefully monitor your Minecraft server's RAM usage.

There are various methods for checking how much RAM a Minecraft: Java Edition server is using. Let's go over each.

Check Minecraft Server RAM on a Linux Server

Linux users can check Minecraft server RAM usage in several ways.

Specify Memory Use When Launching the Server

We can use command line parameters when launching a Minecraft server to keep RAM usage within certain boundaries.

Let's examine the command for starting a Minecraft server on Linux:

          java -Xmx1024M -Xms1024M -jar server.jar nogui        

The command line options –Xmx and –Xms specify the maximum and minimum amount of RAM dedicated to the server. In the example above, we dedicated approximately 1GB of RAM to the server.

Whenever we launch our server, we can adjust these numbers to give it a different amount of RAM. The following command will launch Minecraft server with 2GB of RAM:

          java -Xmx2048M -Xms2048M -jar server.jar nogui        

Check Using the top or htop Commands

We can also explicitly check how much RAM our Minecraft server is using while it's running. To do this, we need a command line utility such as top or htop for monitoring system processes.

top comes preinstalled on most Linux distributions, while htop can be installed with your package manager of choice (aptitude on Debian-based distributions, including Ubuntu).

We also need a way to find the PID (process identifier) number for our Minecraft server process. We can do this in the following way:

          lsof -i:25565 -t        

This command will find a running process that opened a specified local internet port, in this case 25565. Since a Minecraft server uses 25565, the lsof command will output the server's PID.

The lsof command outputs the server's PID

Next, we use top with the PID as a parameter to print memory usage:

          top -p <server PID>        

top will start monitoring the process and display its memory footprint. The columns to look for are:

  • VIRT – displays the total amount of memory used by the process, including memory for shared libraries.
  • RES – displays the resident memory for the process, i.e., RAM usage in gigabytes.
top monitors the process and displays its memory footprint

htop uses virtually the same syntax:

          htop -p <server PID>        

The advantage of using htop instead of top is that the former has a color-coded UI, which makes parsing the information easier.

Check Using Server GUI

Another way to check Minecraft server memory usage is by using its built-in GUI. Launch the server with GUI enabled with the command:

          java -Xmx1024M -Xms1024M -jar server.jar        

Then check the Stats section to find out memory usage.

Check System Load While Running the Server

If you want an overview of your total system load while running Minecraft servers, you can do so using the following commands:

                      vmstat -s                  

Prints memory usage statistics.

          free -h        

Prints memory usage statistics in a human-readable format.

          cat /proc/meminfo        

Prints the content of the meminfo system file to the console.

Check Minecraft Server RAM on a Windows Server

Windows users have two ways of checking Minecraft server RAM usage. They can also limit server RAM usage by launching the server with command line parameters.

Specify Memory Use When Launching the Server

To launch a Minecraft server on Windows, open the Command Prompt or PowerShell and run the command:

          java -Xmx2048M -Xms2048M -jar server.jar nogui        

The command line options -Xmx and -Xms specify the maximum and minimum amount of RAM dedicated to the server. In the example above, we dedicated approximately 2GB of RAM to the server.

Check Using the Server GUI

You can check Minecraft server memory usage by using its built-in GUI. Launch the server with GUI in one of two ways:

  1. By using the command: java – Xmx2048M – Xms2048M -jar server.jar
  2. By double-clicking server.jar

Then check the Stats section to find out memory usage.

Check Using the Task Manager

Another way to check Minecraft server RAM usage on Windows is with the Task Manager:

  1. Press Ctrl + Alt + Delete to launch Task Manager.
  2. Under the Processes tab, look for an entry with "java" in the title.
  3. Check Memory to find out how much memory the server process is using.
