Egads, I'd completely missed the word Windows up there.
I would highly recommend building the postgresql server on a unixish
OS. Even with minimum tuning, I'd expect the same box running linux
or freebsd to stomp windows pretty heavily in the performance
department.
But yeah, the I/O, that's the big one. If it's just a single or a
couple of IDE drives, it's not gonna be able to handle much load.
