FastWorkbench

Overview

This mod is specifically designed to optimize all functions related to item creation in Minecraft. It fixes the issue that appeared in version 1.12, where quick crafting of an entire stack of items could cause temporary game freezes. However, the capabilities of this mod extend far beyond simply fixing this bug.

Accelerated Crafting

FastWorkbench implements a system for caching the last used recipe for all crafting operations. Additionally, it significantly reduces the number of calls to this cached recipe by detecting changes only when items in the crafting grid actually change (unlike the vanilla system that rechecks the recipe with any change, even when stack size decreases). As a result, the number of matching operations is reduced to one instead of possible 600.

Recipe Book

In Minecraft version 1.12, FastWorkbench completely removed the recipe book, which eliminated forced recipe synchronization upon login and significantly accelerated the loading process. In versions 1.13 and above, recipes are synchronized automatically within the new system. In these versions, the mod visually hides the recipe book button by default, but this setting can be changed in the configuration.

Compatibility and Mod Support

The mod integrates via Mixin into PlayerContainer classes (for the 2x2 grid) and WorkbenchContainer (for the 3x3 grid). Any mods using WorkbenchContainer automatically receive all the benefits of FastWorkbench.

Mods that don't use WorkbenchContainer should probably already implement similar optimizations on their own - these improvements are quite simple to implement.
