Hi Culling time is more about amount of nodes\drawables in scene and how they organized into graph, and less about vertices itself. You can try to run your model through osg optimizer with SPATIALIZE_GROUPS option. Also check if you use any cull callbacks with heavy running time. And if you have some nodes on which culling is disabled ( setCullingActive(false) ) deeply in graph structure, this can kill your performance too.
