Overhead for storing each object

I was curious how much space each object affects the sqllite DB's so I uploaded 50,000 0B objects. I performed a "df -B 1" before the upload, and one an hour afterwards (once it stabilized). I was surprised to see that it came to about 250B per object. Granted, that is only about 250GB for 1 billion objects, so it really isn't bad at all. Does this sound about right? I'm also using this to plan out the growth of the account and container services since I want to move them to their own servers.

With our use case, we see about 0.12% overhead on the account and container databases compared to the actual object data. This doesn't count file system overhead of inodes, dirents, etc.

It shouldn't be too bad but also depends on how long your names are, content-type strings are, average object data size, etc.
