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. ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
