FastFurnace

FastFurnace improves the TPS performance of furnaces, blast furnaces, and smokers without increasing smelting speed. It caches the last recipe used and checks it before searching the full recipe registry, making it especially useful in recipe-heavy modpacks. Available for Forge and NeoForge on Minecraft 1.12.2–26.1.2.

Rent your own Minecraft server and install FastFurnace with one click from the server panel to make recipe checks less demanding.
