[Any Version] Insain Recipe Problem

Hello.

I wrote a mod Dynamic Tools (Version 0.0.20) is in Testing mode.

Its Nearly finish.

Now the Problem.

i used "for loops" to doesn't write every recipe by my own.

Now its about 1,8 Mio Recipes (1.800.000 Recipes)

Every Time you craft something its lagging the fps go down to 6.

And do not say go down the recipe.

The name says Dynamic Tools. Without this its not Dynamic.

So how can i make it that the crafting manager is not overloaded?

Thanks Moritz
