Does water boil faster with or without salt?

It comes to a boil slower (i.e. increases the boiling temperature), this increases the possible cooking temperature and so will cause foods boiled in salt water to cook faster. Pure solutions will generally have lower boiling points than mixtures. Adding sugar to the water will have a similar effect but would not be nearly as nice to cook food in!
However, if water is heated up to a high temperature and then the salt is added it could cause the entire pot to start boiling as a result of the salt acting as nucleation sites.
