Clumps is a utility mod designed to improve server performance by grouping experience orbs together. By reducing the number of individual entities the server needs to track, it effectively mitigates lag in high-XP scenarios like mob farms.

It is available for Fabric, Forge, and NeoForge.

Installing Clumps

On AwakeNode

  1. Download the version of Clumps for your server's software and Minecraft version from its Modrinth page.
  2. Open your server's Files tab, go to the mods folder and upload the .jar file. You can also upload it over SFTP.
  3. Restart your server from the Console tab.

On other hosts / manually

  1. Download the correct version of Clumps for your loader and Minecraft version from Modrinth.
  2. Use an SFTP client to upload the .jar file to the /mods folder in your server directory.
  3. Restart your server to apply the changes.

Common issues

  • Mod loader mismatch: Ensure the version of Clumps you downloaded matches your server's mod loader (Fabric, Forge, or NeoForge). Using the wrong one will cause the server to fail to start.
  • Version incompatibility: Check that the mod version strictly matches your Minecraft server version. Using a 1.16.4 version on a 1.12.2 server will result in a crash.
  • Missing dependencies: Some versions of Clumps may require specific API mods. Check the Modrinth page to ensure all required dependencies are present in your /mods folder.

Performance

Clumps is highly efficient and typically reduces CPU usage by lowering the entity count during intense XP drops. Because this mod reduces the number of active entities, it can help stabilise tick times on busy servers.

If you find your server is still struggling with lag, you may need to allocate more RAM. On AwakeNode, simply upgrade your plan and the memory limits will update automatically. If you are on another host, you must manually update the -Xmx flag in your startup command. To add your own JVM flags, set a custom startup command in your server's Startup tab.

Questions

Does Clumps need to be installed on the client?+

Yes, Clumps is a side-dependent mod that generally needs to be installed on both the server and the client for all features to function correctly.

Will Clumps delete my XP?+

No, Clumps simply merges multiple small XP orbs into a single entity, which makes picking them up more efficient without losing any total experience points.

Can I use Clumps with other performance mods?+

Yes, Clumps is designed to be compatible with most standard performance-enhancing mods, though you should always check the mod's specific compatibility notes on Modrinth.

Do I need to change my startup flags to use Clumps?+

No, Clumps works out of the box without requiring any changes to your server's startup flags or JVM arguments.
