How does this program compare to superpi?

You're correct, in that my desktop link is no longer accurate. 1.25 seconds is from my new system, which is an overclocked Core 2 E6600 w/ 2 GB of RAM. I haven't tried it on my old desktop, though with the scaling I've generally seen, it would probably take 2+ seconds on that system.

It's a magnitude faster. SuperPi uses an extremely old algorithm.
