Thiepine
by Apladokimes
Thiepine is a Fabric optimization mod that reduces how often Minecraft allocates short-lived objects during entity and block checks.
What it does
The mod changes how the game handles some per-tick checks, so it creates fewer temporary objects while it compares block touches against entities. Thiepine is published for Fabric only, for 12 release versions 1.21.5 – 26.3, and the latest file is 1.1.2+mc26.3 for 26.3. Either side can run it, and neither needs it. The mod is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license and is not open source.
Key features
Fewer temporary objects
Thiepine stops Minecraft from allocating four objects in each time check where block touches are compared with entities.
Flatter garbage collection
The garbage collector's frametime graph becomes flatter, so frame pauses caused by collection run less often.

Files cover game versions 1.21.5 – 26.3, with the alpha-channel build 1.1.2+mc26.3 as the latest.

What the author says
A small Fabric mod that reduces garbage collection pauses from entity collision checks. It adds a zero-allocation early-exit AABB check before VoxelShape.move() in BlockCollisions and skips a redundant AABB.move() in Entity.collideWithShapes when the offset is zero.
