This mod on its own does not provide any meaningful improvements regarding performance and you probably only want to install it when using a mod that has this mod as a dependency. ### Requirements This port already pre-bundles org.spongepowered and its other dependencies (it.unimi.dsi:fastutil:7.1.0).
