As noted in the [1] wiki page ("Is there any side effect by the patch?" 
section), _aq_dynamic is called every time __getattr__ returns None.
So every time a skin lookup is done (form, page template, script, etc) the 
custom acquisition method will be fired, for example.
I think the first optimisation to do is to have a quick check at _aq_dynamic 
begining to detect cases where it will return None, and do so immediately.
