Aether already caches various bits used for dependency collection but I 
don't know to what degree these caches are employed by m2e or whether 
they even address what you vaguely describe as "processing".

Without something concrete (as in runnable by somebody else) that 
demonstrates your performance issue, I can't help much further.
