Is this the 32M you're calculating?
I really expected more from my comp.

36m 56.157s
P4 641 Prescot @ 3.2 ghz w/ 1 gig DDR2 mem.
SuperPI says only 268 meg mem is allocated though. Might try running it again later on a fresh reboot. I had multiple windows open and was still browsing and working while it ran.
