Smooth Boot is a mod that improves Minecraft multithread scheduling. The result is that Minecraft will load much smoother.

The mod is actually quite simple, it accomplishes this by modifying a few parameters Java offers to tweak parallel execution. This includes the number of threads used by Minecraft executors, and the priority of each thread. There are also some tasks that run faster using one thread compared to multiple threads, so these can be extracted to run on only one thread.

Everything Smooth Boot changes is configurable in the mod config. In the Fabric version, you can edit the config in Mod Menu. The effects are applied after restart. In the Forge version, there is no config GUI, but you can still edit the config in the config folder. The config file is smoothboot.json.

There are current no known conflicts with any mod.

Smooth Boot will work alongside LazyDFU.
