About
Performance tweaks is a mod that contains several optimizations and fixes, ranging from entity optimizations to redstone. Post your thoughts in the comments, for new optimizations you would like to see!
From now on, I am bundling performance tweaks as a multi-platform mod, available for many Minecraft versions. Every optimization will be included, but there will be config options to disable some of them if you don't want them.
Config: (1.2.0+) All config files are now under config/perf-tweaks folder
Dependencies: Because this mod is now multi-platform, Architectury API is now a required dependency
This mod can just be installed on client and server, but works best when installed on both.

Optimizations
Many of these optimizations are no longer updated to modern Minecraft versions, or have additional functionality / configure-ability.
Client Side Optimizations
- Optimization to skip collision checks with many client side entities. (These checks are already handled by the server, reducing the strain on your client.)
- Forked from Corgi_Taco's Entity Collision FPS Fix (Curseforge), (Github)
- Super lightweight, so it should be compatible all mods.
Server Side Optimizations
Optimization to allow mobs with equipped items to despawn naturally. Preserves dropped items when mobs despawn (Configurable)
- Forked from frikinjay's Let Me Despawn mod (Curseforge), (Github). Contains additional configuration options not present in the original mod
- Lightweight tweak that should boost server performance if your world has lots of various entities.
- Configurable mob exclusion list. To make a mob "persistent" just enter
perf_tweaks persistence <mob-name> - If you don't want this optimization, Set
"despawning.enable_despawning_optimization": falsein theperf_tweaks.jsonin the configs.
Optimizations to reduce block updates and power calculations made to Redstone. (Configurable)
- Forked from AC. Credit to SpaceWalkerRS for this fantastic mod: (Curseforge), (GitHub)
- Designed to be minimally invasive to existing Minecraft code, so it shouldn't have any compatibility issues except maybe with mods that significantly alter Redstone.
- If you don't want this optimization, Set
"enable_alternate_current_by_default": falsein theperf_tweaks.jsonin the configs. Additionally, you can disable alternate current for any world by typing commandalternatecurrent off
Optimizations to speed up performance with powered rails. Replaces wasteful recursive method calling with a much faster check by a single powered rail.
- Forked from the mod by FX_PR0CESS: (Curseforge), (Github). The original mod is no longer being updated.
- This mod comprises 1 mixin, so there should be no compatibility issues
