It was commonly believed that adding salt to water lowers the boiling temperature of water and causes it to boil faster, however this was shown to cause such a small change that it was rendered insignificant (however covering the pot will decrease loss of heat and will cause the water to boil faster than an uncovered pot).

What does matter is that you add the salt before you add the pasta.
