New performance documentation released

I've been taking notes on what people ask about on this list, mixed that
up with work I've been doing lately, and wrote some documentation readers
of this mailing list may find useful. There are a series of articles now
at http://www.westnet.com/~gsmith/content/postgresql/ about performance
testing and tuning.

The "5-minute Introduction to PostgreSQL Performance" and the "Disk
performance testing" articles were aimed to be FAQ-style pieces people
asking questions here might be pointed toward.

All of the pieces in the "Advanced Topics" sections aren't finished to my
standards yet, but may be useful anyway so I've posted what I've got so
far.
