I believe they refer to the number of Drawables, Vertices, etc. that are actually rendered. It appears that your slow app is rendering about 4-5 times the number of objects. Perhaps it has multiple cameras or render passes that the quick app does not? Perhaps models are getting added multiple times at the same location? How do the numbers change when you add a single model and how is that change different between the two apps?
