Tpsum
Performance optimization mod improves mob spawning, biome lookup, worldgen allocations, and task loop hot paths.
About this Mod
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.

Tpsum server crashes on startup – what to do?

Is Tpsum compatible with forge and neoforge?
Tpsum officially supports forge, neoforge for Minecraft 1.21.1, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Tpsum – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Tpsum consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
