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.
