that is a misspelling when I was talking to someone about this and it is now the title :3
Hello! If you are reading this and do not know who I am, I am Gamma! I've been running Fabric servers for a while now, and optimizing them for as long as I've been running them. Most of what I've done has been for Fabric servers, and this guide is for Fabric servers. I will not talk about Paper or Purpur or whatever new Bukkit for with plugins. This is for maintaining utmost parity with Vanilla (so no weird Bukkit forks that break technical mc).
The first steps is just the basics. These are mods that you probably already have, but I am listing them anyway!
