I usually turn it down to 2 by default. Lower disk contention increases the
overall speed. If I have a really powerful box, I'll experiment with turning
it up to 3 or 4. That said, I have a quad Xeon with a 3ware 9550 disk
controller and 4GB RAM, and still running it with only 2 concurrent jobs
allowed. (I must have determined at some point that 3 concurrent jobs wasn't
worth the disk thrashing).

Your Mileage Will Vary.
