Noisium (Unofficial forge port)
by coco875
Noisium speeds up world generation for Forge servers, and only the server needs to run it.
What it does
The port changes several world generation functions that other optimisation mods leave alone. The largest change is to the populateNoise step of NoiseChunkGenerator, which places blockstates while new chunks are generated. Instead of calling the usual block-setting routines, blocks are written straight into the palette storage, which skips work that Minecraft normally performs when a block is set and that only slows generation down.
Three smaller optimisations target biome population, chunk loading and the sampling of blockstates used during generation. The author reports a 20 to 30 percent gain in generation speed, measured in a benchmark on a Fabric build. The mod is built for Forge and has the 1.0.2 build for 1.19.2 as its latest file, published on 2023-12-18.
The mod keeps full 1:1 parity with vanilla world generation, so worlds made with it match those made without it. It is released under the GNU Lesser General Public License v3.0 only and is open source, with the source code and issue tracker publicly available.
Key features
Faster blockstate placement
Blockstates are written directly into palette storage during chunk generation, which reduces overhead on each block.
Faster biome population
A dedicated optimisation speeds up the step that fills chunks with biomes as they generate.
Faster chunk loading
Chunks become ready sooner in the generation process through a separate optimisation.
Faster blockstate sampling
The speed of sampling blockstates used for generation is improved by its own change.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Exploring new terrain
Players who travel into unexplored areas generate chunks quickly, with terrain identical to vanilla.
Pre-generating worlds
Server owners who generate large areas ahead of time can finish the job in less time.
Who it’s for: Server owners who want faster chunk generation without changing the terrain players see. The mod suits servers that already run other performance optimisation mods and need the world generation gaps filled.

What the author says
The improvements lie between a 20-30% speedup when generating new chunks in vanilla Minecraft (benchmarked on 1.20.1 Fabric). Noisium changes some world generation functions that other mods don't touch, to fill in the gaps left by other performance optimisation mods. Most notably, NoiseChunkGenerator#populateNoise is…
