Fast Workbench Mod 1.14.4/1.12.2 is a simple mod that makes the crafting table in Minecraft run faster and cause less network traffic. It also introduces some interesting features.
It works by caching the last recipe used and check the recipe before it rescans the entire registry. This process is said to operate much faster than the original one and also lower network traffic.
It has a third function: disabling the recipe books and let it do completely nothing, which will reduce network traffic to prevent wasting. However, the mod only applies to the vanilla workbench and has no effect on other crafting station mods.
