How should I set up Ultra Fast Optimization for players and a server?
Use Ultra Fast Optimization 1.21.10-NeoForge-1.0.1 as the pack version. Install the pack as its own launcher instance. The creator’s listing does not name a separate server file, so check the release notes before setting up a dedicated server. Do not upload the ordinary client folder blindly.

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 Ultra Fast Optimization?
Ultra Fast Optimization 1.21.10-NeoForge-1.0.1 on NeoForge. The pack contents and setup notes below stay tied to that release.
The selected pack release is Ultra Fast Optimization 1.21.10-NeoForge-1.0.1. That file is for Minecraft 1.21.10 with NeoForge 21.10.64. This NeoForge setup needs Java 21. It contains 20 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.
