Lomka
by Starlev
Lomka is an optimization mod that cuts redundant garbage and memory allocations in the game's rendering, sound, font and resource loading code.
What it does
Lomka mixes a set of small optimizations into Minecraft. Its main purpose is to reduce the number of redundant garbage allocations, which lowers memory use and can make frame rates steadier. Fewer stutters and slightly faster resource loading and world generation are reported by the author, who also notes that benchmarks were run on isolated microbenchmarks under JDK 25.
The project code was created with help from Artificial Intelligence, and the mod is open source under the GNU Lesser General Public License v3.0 only. Files cover 1.7.10 – 26.3 across Fabric, Forge, NeoForge, Quilt and Ornithe. Forge builds for 1.8.9 and 1.12.2 need MixinBooter 11.17, and Forge builds for 1.7.10 – 1.12.2 need UniMixins 1.7.10 as the mixin runtime. Ornithe builds ship their own mixin runtime, so they need nothing extra. Either side can run it, and neither needs it.
Key features
Fewer allocations
Rendering, collision loops, vertex writes, pose stacks and entity code reuse objects instead of creating new ones each tick.
Cached font and texture work
Font glyph advances are cached, and texture atlas animations advance only when they are needed.
Lighter sound and resource handling
Playing sounds skips an unneeded wait on the sound thread, and resource scanning reads cached pack metadata.
Bulk NBT reads
Saves load blocks and world data through bulk array reads instead of per-element stream calls.
Native buffer and mip handling
Generated mip levels are released after upload, and native buffer reallocations are reduced during audio streaming and mesh building.

How it compares
Jasione is also an optional client or server mod under the GNU Lesser General Public License v3.0 only, with files for 1.18.2 – 26.3 on Fabric, Forge, NeoForge and Quilt. Redirected is open source under the same license, but its environment is client and server, so both sides must run it, and its files cover 1.20 – 1.21.1 on Fabric, Forge and NeoForge. Lomka's optional environment means either side can run it alone.
