Tpsum
ModrinthPerformance optimization mod improves mob spawning, biome lookup, worldgen allocations, and task loop hot paths.
Tpsum is a small, performance-focused optimization mod for Minecraft (Forge/NeoForge).
It targets hot paths that are executed extremely often during normal gameplay (server tick, mob spawning, biome lookup, and worldgen), aiming to reduce CPU time and avoidable allocations/GC pressure.
