ServerCore

A mod that aims to optimize the minecraft server. Works on both dedicated servers and singleplayer! Several patches & optimizations to improve performance and reduce lagspikes, which shouldn't make any noticeable changes during gameplay. Many configurable features that can heavily reduce lag, but have a slight impact on gameplay depending on the configuration. By default, ServerCore should not alter vanilla behavior. Features that do are disabled by default. It is advised to configure this mod to your own requirements for the best balance between speed and behavior. A lot of the optimizations in this mod are focused on getting rid of the majority of random lagspikes on servers. Other than that, it also includes plenty of optimizations for things like chunk ticking, mob spawning, item frames and player logins. Entity Activation Range A very configurable feature that allows you to drastically cut down on the amount of entities that have to be processed on the server. This is a port based off of Spigot's and PaperMC's implementation, but more configurable with additional (optional) features. Dynamic performance checks Allows the server to automatically adjust the current settings depending on the tick time and config. These include: Chunk-tick distance, View distance, Simulation distance & Mobcaps. Villager lobotomization Allows the server to cut down on villager lag from large trading halls, by making villagers stuck inside 1x1 spaces tick less often. More configurable mobspawn...
