QuantumChunks
by Mental
QuantumChunks changes how a busy Forge server prepares chunks, spreading the work across CPU cores by region.
What it does
The mod routes chunk preparation and generation through a smart worker pool that runs in parallel across the available CPU cores. Vanilla tends to handle this work on a single thread, which slows down servers where many players explore at once. Work inside the same 32×32 region is kept serialized so worlds stay safe and stable. Only the server needs it, so players join without installing anything. Files are published for Forge, for 1.20.1, 1.20.2, 1.20.3, 1.20.4, 1.20.5 and 1.20.6, with 1.0 for 1.20.6 as the latest file.
Key features
Multi-core chunk loading
Chunk loading is split across CPU cores while respecting region boundaries.
Region-aware scheduling
Work in the same 32×32 region runs in order, which keeps world data consistent.
Smoother ticks
Aimed at fewer tick-time spikes in busy moments. Spark can measure the effect.

Multi-core, region-aware chunk loading for busy Forge servers. When many players explore, vanilla tends to pile chunk work onto a single thread. QuantumChunks routes chunk preparation and parts of generation onto a smart worker pool, parallelizing across CPU cores while serializing work inside the same 32×32 region…
