Ah ... you're on a Mac ... Intel or PPC? If Intel, you might want to
look into their VTune tool (I think it runs on MacOS). Even if you don't
have the latest whiz-bang multi-core Intel chip, VTune will tell you
stuff you probably never knew you should care about.
(I'm an Intel-free zone, and so I use AMD's CodeAnalyst.) :)
Database, eh? Maybe you should be recompiling the database from source
too. PostgreSQL? MySQL? There are *lots* of tweaking gizmos for them,
plus a benchmark called "MySQL Super Smack".
