I think the difference isn't raw speed, it's efficiency.

I know every year I'm better able to stop before I go down too far on the wrong path to solving some problem, because I learned many times in previous projects how that type of solution would end up hurting me in the end.

So less time spent on fruitless efforts, more time spent on fruitful efforts, and in the end usually a better, more maintainable solution, to boot!
