I doubt seriously you'll be able to magically speed things up. Find isn't a slouch. There's only so "fast" you can make an exhaustive search. Now... if you can change the logic of whatever you are doing so that there is a way to do a fast lookup of the file, then fine...
(e.g. whenever I create a *.aps I create a name-value pair in my high speed indexable database... or something else)
