I've read that a long stroke relative to rod length increases stress on certain engine components. Does this mean that it increases friction?

Are we talking rod/stroke ratio, or absolute stroke length? Can you have a good rod/stroke ratio and still approach an "ideal" stroke length simply by building a bigger engine?

Also, why does increased stroke length increase efficiency anyway?
