Only if you know how long it will take to render a frame. If you render "as fast as possible (to a max of xyz hz), you get better worst case performance than if you delay compositing. A render time of 2 physical frames results in only 1 missed frame instead of a render time of 1.26 physical frames resulting in 2 missed frames. Of course nothing is simple in the real world, the flip side is rendering the extra frames creates waste heat that slows down modern processors with insufficient cooling.
