Pack setup

How should I set up How Optimized for players and a server?

Client instance Install How Optimized 1.0.4

Dedicated server setup Match How Optimized 1.0.4

Pack loader Fabric 0.18.2

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 How Optimized?

How Optimized 1.0.4. Change the pack release and its contents or setup may change too.

31 mods in this pack file

The selected pack release is How Optimized 1.0.4. That file is for Minecraft 1.21.11 with Fabric 0.18.2. It contains 31 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.
