Pack setup

How should I set up Optimize My Server! for players and a server?

A pack is a matched client and server setup, not one mod with an install-side label. Keep its release, loader, manifest and overrides together.

These numbers come from the pack file you chose. “Not labelled” means we don’t know which side it belongs on—not that it is safe everywhere. The file count is not a RAM estimate.

What are the server requirements for Optimize My Server!?

Optimize My Server! 26.3.0. Change the pack release and its contents or setup may change too.

17 mods in this pack file

The selected pack release is Optimize My Server! 26.3.0. That file is for Minecraft 26.3 with Fabric 0.19.5. It contains 17 mod projects. The creator’s listing does not name a separate server file. Check their notes before using one, and do not upload an ordinary client folder or rebuild the pack mod by mod. A file count cannot tell us the right RAM, CPU or storage; size the server for the players and world you actually run.

About this project

What kind of pack is Optimize My Server!?

What is this?

It's in the name! It uses mods to optimize your Minecraft server's performance and reliability.

It also includes mods that prevent x-ray and are server-breaking.

How do I install?

Load the modpack into a supported launcher. Copy the mods from the mod pack instance's folder and paste it into your server's mod folder. This is currently a Fabric-focused modpack.

There is a NeoForge version in this project, but mod support is limited so it is more cutdown.
