Mobtimizations Mod (1.20.1, 1.19.2) – Entity Performance Fixes

Mobtimizations Mod is a server optimization mod aimed at reducing the impact of entities on performance. It optimizes or disables certain mob pathfinding algorithms by default, significantly reducing their load on the server. It optimizes a lot of tasks that Entity AI wastefully performs, minimal effect on gameplay.

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.
