Lon
by nilcil
Lon is a lightweight optimization mod that reduces chunk-loading lag and keeps memory use low on modest hardware.
What it does
Lon targets chunk-loading stutter through pre-generation and monitoring, and it tunes memory use with automatic garbage collection and entity cleanup. Its aim is to keep the game responsive on low-end PCs. Native support covers both Fabric and NeoForge, and installation means dropping the JAR into the mods folder. Only the client or the server needs it, so either side can run it without the other.
Key features
Chunk pre-generation
Generates chunks ahead of time so that exploring causes less loading lag.
Memory and entity cleanup
