OptiServer

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.
