Do you add salt to boiled water for pasta?

Adding salt actually increases the boiling point. I've heard the rumor that it makes the water boil faster many times now, and the thought struck me in a chemistry class that the rumor was wrong, so I decided to investigate. Adding a soluble/nonvolatile substance (like salt) to any solution decreases the freezing point (think salting roads) and increases the boiling point.
