Currently we only know the aggregate number of objects in the render tree.

Following bug 88579, it would be nice to know how many RenderLayers an average page has. This would give us some idea how much savings shrinking RenderLayer could yield to. While at it, it may be worth considering a finer grained counting of other types of RenderObject (RenderBoxes, RenderBlocks, ...)
