Shadows done the traditional way with shadow volumes are pretty expensive: Two passes through the scene graph for objects and 2 passes for the shadows. I'd guess that reflections are about the same expense. But, there are many short cuts, especially for relatively static scenes like the moon or sun reflecting on the water.
