I'm currently evaluating swift for object storage, to replace our MogileFS storage system, which is currently hosting approximately 75 million objects and growing rapidly. I can of course split these out over multiple containers, and scale the amount of container servers (which we will probably do). But I was wondering if anyone had some real world experiences as to when the amount of objects in a single container becomes a performance bottleneck (if I understand the architecture correctly, hosting the database for a single container is not sharded across multiple container servers).
