About Tpsum
From 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.
⚠️ No new content - Tpsum only improves performance.

- Mob spawning (NaturalSpawner) optimizations
- faster spawn checks and fewer expensive calls in the spawn hot path
- Faster biome lookup
- cached noise-biome source and small math hot-path improvements
- Reduced worldgen allocations
- pooled feature placement context to lower GC load
- Task loop improvements
- optimized
BlockableEventLoopqueueing/counting for high task throughput
