Sorry for my stupid question;)

If you have 12 threads, it's 12 threads and not more.

I guess there needs to be some kind of dependency between your new recipes.

make -j can use as many cores as you like even with a single recipe.

How would it speed up builds if you break up a recipe into multiple recipes?

What is your refactoring approach?

le *sigh* ...
