The type of ball used and the mass of the ball also affects the amount of friction between the ball and the lane. Typically, a ball speed at release of less that 17 mph is considered slow, 17 to 19 mph average, and greater than 19 mph is considered fast. I have read of a maximum ball speed measured at 25 mph, but I am not sure of this.
