Tested using 4 fluid crafters. First screen shot is the performance while crafters are running fully stocked:

Second screen shot shows same 4 crafters running while missing 1 ingredent (and therefore not crafting anything):

You can see the fluid crafters take up over 3x as much tick time while not preforming any actual operation. IIRC, MFR used a longer cool down on machines after a failed operation, maybe a similar system could be used to keep crafters from being so aggressive with checking if it can craft.
