In general, our users will complain if code size increases, even by a trivial 
amount. It is only rarely (or never) that I hear a complaint that the code is 
not fast enough. And even then, they typically talk about speed of executing an 
ISR, not mainline code.

Because of that, IMHO, size of the code is much more critical than speed.

Having said that, though, I'm not against having additional, alternative 
functions that optimize speed, as long as the default is for size.
