COSS grabs all the obvious small objects into a separate small and efficient store, leaving the rest assumed to be large for the main store. Alex is working very hard at getting the RockStore feature working, which a part involves fixing the COSS support in 3.x. Any help able to be provided to him in that project is very, very welcome.
