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 Sensei's FPS Boost?
Sensei's FPS Boost 1.21.1. Change the pack release and its contents or setup may change too.
The selected pack release is Sensei's FPS Boost 1.21.1. That file is for Minecraft 1.21.1 with Fabric 0.17.3. It contains 30 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.
