There isn't any example that address this right now. You could modified the osginterstion example to add a command line option for enabling the build of kdtree's and then use it as a benchmarking tool. When developing the KdTree support I did plenty of benchmarking but I never truned these tests into a OSG example and don't have the code anymore unfortunately - I do lots of prototype/testing so don't tend to keep all the tests around. From my experience KdTree's help most when the scene graph is composed of large osg::Geometry meshes - here it can be 10 to 1000's of times faster, if the scene graph is already very fine grained with many small osg::Geometry meshes then the difference is much smaller.
