It was just a generic question about general approaches to achieving performance
optimization over a wide range of parameters for a wide range of algorithms.
I guess I could imagine things like cache awareness being dumped into allocators
or something. Not sure if there is a general approach for picking specific
implementations of any class of algorithms. I guess I'd be asking about something
like a "strategy" API perhaps. Maybe the question as posed doesn't make a lot of
sense as I am asking for a general approach to handling ad hoc logic 
that you could hide in your own factories without furhter thought :)
