Noisiumed
by imbavirus
Noisiumed is a server-side optimization mod that speeds up terrain generation for new chunks while leaving the resulting world identical to vanilla.
What it does
When a server creates new chunks, Noisiumed reduces the time spent on the internal steps Minecraft uses for terrain. Exploring fresh areas, rendering level-of-detail terrain through Distant Horizons, and running a busy server all benefit from shorter generation times. Block placement, biome assignment and structures stay exactly as vanilla produces them, so only the speed changes.
Installation needs nothing beyond dropping the JAR into the mods folder, since no configuration is required. Only the server or the singleplayer host needs it, and players joining a server do not. The mod is published for Fabric, Forge and NeoForge, with files covering 14 release versions, 1.20 – 1.21.6. It is released under the GNU General Public License v3.0 only and is open source, with public source code and an issue tracker.
The project is a maintained fork of Noisium by Steveplays28, whose original was archived. It keeps the work running and applies small fixes where needed, and it also targets a version that other forks do not currently support. Other mods such as C2ME, Lithium, Sodium and Nvidium can run alongside it. Biospherical Expansion (BioX) is a known incompatibility.
Key features
Faster block placement
Writes directly into chunk palette storage, skipping overhead that the generation process would otherwise repeat.
Improved biome population
Changes memory access patterns during biome assignment so the step completes sooner.
Cached generation values
Keeps frequently used generation results in storage rather than recalculating them for each chunk.
Lighter chunk locking
Lowers the synchronization cost incurred while noise is populated into a chunk.
