About this Mod
Server optimization mod focused on entities, reducing their impact on your server while keeping change in gameplay to a minimum.
Features:
- Reduces the rate of expensive mob wander pathfinding, even more so if far from players.
- Reduces how often the expensive enemy targeting tasks are run.
- For monsters, disables the expensive 3x3x3 hazard scanning that is constantly running every tick while path following, your pets are safe.
- Disables the frequent pathfinds done while already following a path.
- Reduces the expensive searching done to find a turtle egg to crush, for zombies/husks, by default fully disabling it.
- Optimizes the expensive zombie village raid task that scans around a lot for villagers, by default cuts the chance to 1/3.
- Wander pathfinding and enemy targetting are further reduced when the mob is not near a player.
- Each feature can be configured on/off, and some further with chance to cancel an attempt.
Demonstration:
With each test I had lots of extra mobs spawned - On my 20 core i5-13600K I kept 1000 monsters spawned to stress the server.
