I suspect that the issue is too complicated for there to be an official threshold which everyone can rely on. It's not just a question of whether the filesystem or database can serve up the data faster. It's also the impact that those large chunks of binary data have on the database engine's cache, and what that's doing to performance globally. Presumably the specifics of that impact will depend heavily on the data access patterns of the application in question.
