OptiServer utilizes the most- and less-common optimization mods, and if you use this modpack on your server, you can experience much more performance, and more free resources. This modpack is for fabric, but I included Cardboard in it, so you can use most Bukkit/Spigot/Paper plugins, for those who want to use them.
This modpack optimizes the game in:
- Chunk load
- Bugs
- Drops
- Mob despawn rules
- Light engine
- Memory
- Nether Portal
- Player
- Inactivity
If you don't want any of these, feel free to modify the modpack.
