Server optimization mod that was originally created for the DeceasedCraft modpack to help with their high entity counts. The mod is 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.
