Carpet ROF Addition

The mod targets server performance, and it changes vanilla mechanics when its default configuration is used. Several of its optimizations focus on ender pearl cannons, where it reduces lag from ender pearl flight and improves how ender pearl tickets behave. TNT movement explosions, along with the lag and storage they cause, are reduced by merging TNT and explosions. Raycasting and explosion handling are also optimized.

Asynchronous Random Ticks is the largest change. It rewrites the random tick mob spawning logic through caching and asynchronous processing, which lowers idle MSPT on servers with many loaded chunks. Mob AI processing is delayed and limited to reduce lag, and entity particle packets are limited in certain extreme situations to cut bandwidth use. Because it replaces core spawning logic, the mod is likely incompatible with other rules mods that change the same systems. Some features offer multiple adjustable levels so normal machine operation is preserved, and the mod provides some debugging commands.

The mod requires Exceed Chunk Marker (ECM) on the server. It runs on the server only, so players join without installing anything. Files are published for Fabric, for 17 release versions 1.21 – 26.3, and the code is released under the MIT License as open source.
