FastSuite

by Shadows-of-Fire

FastSuite speeds up recipe matching on Forge and NeoForge by indexing recipes so only viable candidates are tested.

What it does

Recipe matching is the lookup the game runs whenever a crafting or processing screen needs to know which recipes fit the current inputs. FastSuite replaces the full-list scan with an index-based algorithm, so for any given input only candidate recipes are checked. In the author's benchmarks this matched all recipes for an input roughly 2x to 4.5x faster than vanilla, with no threads and no per-match data writes.

The project has gone through three approaches. Versions 4.0.0 and older reordered a move-to-front list, versions 4.1.0 through 6.x spread matching across threads for recipe types with more than 100 recipes, and version 7.0.0 onward uses indexing. The author notes that vanilla got faster over time, which narrowed the gain from threading, so the indexed approach is the one still in use.

FastSuite requires Placebo on both Forge and NeoForge. Installation covers the server and each player's game. Files are published for 1.20.1 and 1.21.1 on Forge and NeoForge, plus a 26.1.2 build, and the code is open source under the MIT License.

Key features

  1. Indexed recipe lookup

    Recipes are indexed so the matcher tests only candidates that can apply to the given inputs.

  2. No per-match data writes

    The indexed matcher runs without writing data on each match, so it adds no extra state per lookup.

  3. Vanilla recipe behavior

    Matching still returns the recipes the game would find, while the search itself is faster.

  4. Non-intrusive design

    The author built the mod to avoid changing other systems, which helps it sit alongside other mods.

Requirements

Dependencies declared by the latest file for each loader.

Required 1

PlaceboPlacebo is a library used by most of my mods. It does not provide any game-relevant features on its own (save for maybe a couple debug commands).

Use cases

Large modpacks

Packs with many recipe types and recipes can spend less time on each crafting or processing lookup.

Questions

Does FastSuite need Placebo?

Yes. Placebo is a required dependency and must be installed alongside FastSuite on Forge or NeoForge.

Does FastSuite have to be installed on the server too?

Yes. A server running it needs every connecting player to have it too.

Which game versions have files for FastSuite?

Files exist for 1.20.1, 1.21.1 and 26.1.2. The latest Forge file is 5.1.2 for 1.20.1, and the latest NeoForge file is 1.21.1-6.0.7 for 1.21.1.

What the author says

FastSuite improves recipe matching performance for every mod that uses the JSON recipe system, rather than a specific subset of recipes. Its approach has changed across major versions — the current implementation (7.0.0+) uses an index-based algorithm. List Reordering (4.0.0 and older) — Recipes were stored in a…
