Qiu's Optimization
by qiuym
Qiu's Optimization is a Forge mod that lowers server CPU load by batching tile entity work, caching results and throttling entity AI.
What it does
The mod targets server-side performance on Minecraft Forge. Three mechanisms run together: batch processing of tile entities, caching of tile entity updates on a configurable rebuild interval, and AI throttling for entities that do not need a full update each tick. A dynamic TPS adjustment also lowers the target tick rate when the server is under strain, which keeps responses steadier. The author describes the design as lightweight and non-invasive, aimed at reducing CPU cost on Forge 1.20.1 servers.
The mod is released for Forge only, across 12 game versions 1.18.2 – 1.20.6, and it is needed on both the client and the server. Installing it means placing the file in the mods directory and starting the game or server with Forge 47.4.4 or later. The config file exposes an entity mode with BOOST, REDUCE and PRESERVE settings, plus options for item merging, staggered chunk saving and the tile update interval. Configuration changes take effect only after the server is restarted. The code is not open source, and public links exist for the source code.
Key features
Tile entity batch processing
Tile entities are processed in batches, spreading the work across ticks instead of handling each one at once.
Entity AI throttling
Entities are throttled by AI so their updates run less often when a full refresh is not needed.
Entity mode setting
The entityMode option selects BOOST for vanilla entity behavior, REDUCE to save more CPU, or PRESERVE to keep the current balance.
Staggered chunk saving
An option spreads chunk saves across multiple ticks, which can smooth out pauses during saving.
Configurable update interval
The tile update interval is set in ticks, with a default of 20 and a range of 5 to 200.

Use cases
Who it’s for: Server owners running Forge 1.20.1 or another supported version who want to reduce CPU cost without changing how the game plays. Players who only use single-player need it on the client side too, since the environment is client and server.
