Quick answer
Which OptimizedSMP release should I use?
Latest stable file OptimizedSMP 1.21.10_2
Game version 1.21.10
Loader Fabric 0.17.3
OptimizedSMP 1.21.10_2 is a complete pack release for 1.21.10 with Fabric 0.17.3. Install it as its own launcher instance. If the creator publishes a separate server file, make sure it names this exact pack release. 27 mods in this pack file.
Pack setup
How should I set up OptimizedSMP for players and a server?
Use OptimizedSMP 1.21.10_2 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.
Client instance Install OptimizedSMP 1.21.10_2
Dedicated server setup Match OptimizedSMP 1.21.10_2
Pack loader Fabric 0.17.3
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.
Referenced mods 27
Client only 11
Server only 1
Not labelled 15
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 OptimizedSMP?
OptimizedSMP 1.21.10_2. Change the pack release and its contents or setup may change too.
The selected pack release is OptimizedSMP 1.21.10_2. That file is for Minecraft 1.21.10 with Fabric 0.17.3. It contains 27 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 OptimizedSMP?
Pack Description
This pack includes a carefully selected set of optimization mods to keep your server running smoothly, paired with beautification enhancements to improve visuals without compromising performance. Designed specifically for small-scale SMP servers, it strikes the perfect balance between efficiency and aesthetics. Completely Vanilla friendly (i define that as 'if i remove this pack, can i still run the world in vanilla minecraft?).
I personally use this setup for my SMP, but feel free to use it for your own server.
