If you attach the StatsHandler to your OSG viewer you can call up some statistics on your scene graph (overall, and per camera view). It will detail you the number of geodes, transformations, drawables, vertices in the scene graph and also the total count of rendered instances thereof.
Listed under drawables you will see more detail whether these drawables are actually triangles, quads, polygons, etc.. and if they are "fast" drawables or some that run slower code paths (e.g. those that run through a depth sorting because they are in the transparent render bins. Also the plots at the top of the screen will detail the execution time of various phases of the rendering process (cull traversal, draw time, etc...)
