For some apps you can see improvements by reducing function calls in the
order of thousands or even just hundreds, never mind millions. I've seen
real-world measurable speed ups by manually inlining methods and
otherwise reducing function calls by using pointers. I mean "seen"
literally, saving just a few milliseconds per frame in a game really adds
up for example - even a seemingly modest 10FPS jump can turn an
unplayable game into an enjoyable experience.
I deliberately used an example of which the code (incrementing a counter) is
among the simplest to achieve for a compiler. Therefore, I figured, measured
time would most effectively and truthfully render the overhead of a function
call over longhand code.
Now, I'm not familiar with gaming (I don't even play computer games, let
alone create them), and I'm not sure I follow you when you speak of reducing
function calls by using pointers to create a significant speedup. I just
don't see where the speedup would have to come from. Could you give an
example?
