Have a look archives/forum into discussions about osg::ProxyNode and osg::PagedLOD as these are design for dynamic datasets. With PagedLOD database you can scale comfortably up to multi-terrabyte databases and still hit 60Hz. However, it does require you to build an appropriate PagedLOD hierachy, something that is a more advanced topic. The other approach is to reduce the size of the individual models you are loading. You don't say anything about what form these models take so I can't make any specific suggestions. General suggestions are use compressed textures, use Vec4ubArray for per vertex colours instead of Vec4fArray, simply the meshes, use osg::Texture::setUnrefImageAfterApply(true).
