For optimal performance a balanced quad tree is typically best for scene graph applications, while groups containing a large number of children breaks this efficiency forcing the traversals to visit all children all the time. The osgUtil::Optimizer::SpatializeGroupsVisitor can be used to reorganize large flat groups of children into a quad tree. You can call this visitor on it's own or as part of the wider Optimizer::optimizer(Node*,int options) operation if you include the osgUtil::OptimizeSPATIALIZE_GROUPS bit mask to the options parameter. The class can be found in include/osgUtil/Optimizer.
