This may be a bit of a newbie question but here goes anyway.
I'm writing a very cpu intensive program and therefore want to optimize as much as possible. I just wanted to know if passing objects by pointer is faster than passing them by reference. It would seem to me that both methods should be about the same, but I would like the opinion of someone more knowledgeable than myself. Thanks.
I e-mailed bjarne stroustrup (creator of c++) about this a year ago, and he said there's no difference.

Remember that access through a reference will involve exactly the same machine
operations as access through a pointer for equivalent uses.
