I imagine with as many objects as the tree macro produces a LOT of bounding
boxes must be computed. It will sure help with the final render time but
the parse time suffers as a result. The amount of time to compute the light
buffers will also increase when there are many objects present in a scene.
Manual bounding might help with this but be sure to turn off automatic
bounding if you do or POV might just ignore your bounding.
