Performance Optimization

Overview

ModernFix's Performance Optimization feature groups several tweaks that speed up game startup and world loading. It makes blockstate caches rebuild only when their data is actually needed, caches resource pack listings to cut down on slow file checks, and moves resource and data pack reloading onto dedicated worker threads. It also delays data fixer initialization until an upgrade is required, and on certain versions avoids redundant datapack reloads and applies chunkloading and biome-related improvements.
