Stirring results in the salt dissolving more quickly.
Explanation: stirring increases contact between fresh solvent and the salt and removes the thin layer of saturated solution at the salt surface, so mass transfer to the bulk is faster. Stirring changes the dissolution rate (kinetics) but does not change the equilibrium solubility at that temperature (unless stirring noticeably changes the temperature).
