What is the actual effect of adding salt to water *before* it starts boiling, regarding speed?

Answer

It slows down the process slightly by raising the boiling point.

Adding salt increases the boiling point of water. Because the water must reach a higher temperature, it requires more energy absorption, which slightly delays the time it takes to begin boiling.
