The selected pack release is Beta 4 (1.21.9) Echo Performance 1.3.3. That file is for Minecraft 1.21.9 with Fabric 0.18.1. 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.
