[TriLUG] tuned tunings

[Lee Fickenscher via TriLUG]

LOL! That's hilarious. Thanks for the laughs. :D
On the serious, I'm not evaluating Mongo, I got hired on in a shop where
it's already in production and has been for a while.
I'm not sure why it was chosen over other options, but it's been working
for them for the last 5 years or so.
I'm just cleaning up, updating, and documenting the existing system.
