Fast Recipe Search

latest version of this mod requires installation on both the client and server sides (except for the Fabric version).

This mod dramatically increases recipe lookup speed. Its core mechanism builds a tree index based on the hash codes of recipe ingredients, where ingredients serve as branches and recipes as nodes. When searching, it first extracts the ingredients from the container and starts matching from the root node; if a certain key does not match, it prunes that branch directly and no longer searches it, until a fully matching recipe is found. This greatly reduces the number of recipes that need to be checked. Compared to the vanilla method of comparing recipes one by one, it speeds up by more than 10 times, and the performance advantage becomes more significant as the total number of recipes increases.

Compatibility:

This mod is compatible with all mods that use the vanilla recipe manager for recipe searching. It is completely incompatible with Recipe Essentials (or FastSuite) because they optimize the same module. According to my test results, installing this mod alone achieves the best effect — it provides better optimization performance while ensuring compatibility.

Recipe Essentials relies on a caching mechanism (which often performs poorly), while FastSuite uses parallel processing (distributing the performance cost across multiple threads and potentially causing compatibility issues).

FastFurnace, FastWorkbench, Client Crafting are compatible.

Configuration:
Because some mods implement recipe-related interfaces in a non-standard way — for example, they implement the getIngredients method of the Recipe interface, so ingredients can be extracted and thus are optimized by this mod, but the corresponding Container interface does not implement the getItem method, making it impossible to search for that mod's recipes.

To address this issue, this mod by default only optimizes vanilla recipe types (crafting table, furnace, etc.). If you need better optimization, you can try turning off the "optimize_only_vanilla" option.

In vanilla:

• Recipe searches are 8.36x to 85.95x faster
• Most basic recipes see improvements between 8-40x
• Failed matches are handled 28.11x faster

In ATM9 (heavy modpack):

• The improvements become even more dramatic, ranging from 133.19x to 6942.47x faster
• Basic recipes like sticks and crafting table see improvements of over 5000x
