Cull and draw can only run in a parallel once all the dynamic geometry has been dispatched, otherwise the draw will be dispatching data that is being modified by the next frames update and cull traversals. Perhaps you have some dynamic geometry or StateSet's that are holding back the next frame. Regardless of threading of cull your problem is draw dispatch not cull, you need to look into why the draw dispatch on the second draw is taking so long. Please look at my last email.
