Iterating over the 5000 children would be pretty slow - what if you could discard some of these children without even looking at them? A hierarchy of sorts, where you can ignore large swaths of those children, would help... Consider, for example, using a k-d tree: http://www.openscenegraph.org/index.php/documentation/user-guides/107-kdtrees
Or you can do this on your own, if you like, by grouping nearby nodes into their own osg::Group. Depends what your underlying data looks like. I would not recommend combining the geometry into a single drawable unless you expect all of them to be visible at once, and that each piece of geometry is fairly small.
