Alternative Chunkloading

In vanilla 1.7.10, requesting a block or block entity loads the chunk it sits in, and the loads can cascade into further chunks. The mod uses a vanilla toggle on the ChunkProviderServer instance to stop that automatic chunk loading whenever a block entity is requested. Chunks then load only when they are loaded explicitly, for example through loadChunk x y z or through chunk loading tickers, which keep working as before.

The mod is server-side only, so players join without installing it. It requires UniMixins, and it is published for Forge 1.7.10 with the 1.4.6 file. Its configuration has a loadChunkOnProvideRequest option that is true by default, and setting it to false limits loading to explicitly loaded chunks through the WorldEvent.Load event. A disableChunkLoadingOnRequest option controls the vanilla toggle and is also true by default. A separate autoLoadChunksOnTicketCreation option is set to true by default.

The author notes that some cases, such as multiblock structures from other mods, may still cause lag, and that the mod mainly aims to help with performance slightly. The source code and issue tracker are public, and the code is released under the MIT License.
