Any Domino sample database?

In IBM DB2 Express-C, you can automatically create a sample database with lots of data. I am looking for a sample NSF sample database also, so I can show our Dojo integration techniques. Unfortunately, I haven't found one yet, even in Google.

If my memory serves me right, I saw a sample NSF database years ago containing many sample names, but I can't seem to find it again.

It is obvious that I cannot post the NSF of my current employer. So I hope someone could show me where I could get a sample NSF database with lots of data. It is important that it contains lots of data to show you the difference between XML and JSON in terms of speed.
