As Carsten already said, that renders the whole subgraph under that
node.

No, the actual rendering process is totally hidden inside the
RenderAction, the SSM won't help you here.
I'm not quite sure why you need to traverse the graph yourself. Just
measuring the time for the graph with the unwanted nodes switched off
should give you acceptable results. What do you need to do during
traversal?
