I didn't know where to put this thread, so I just put it here. Someone posted a link to a cool application called piX that tests your system by calculating certain decimal numbers of Pi. So I thought it is a cool oppurtunity to test your systems performance. First, download the program here: http://www.coriolis.ch/en/pix/ The website claims that a 733Mhz G4 calculates 100,000 decimals in 16 seconds, and that same number in 5 seconds on a 2Ghz Core Duo. So, I guess how we can do this is by posting your machines specs, and then running the program at 100,000 and 250,000 decimals, just to see how your system runs under different numbers. When it is done, scroll down to the bottom of the page and it tells you how long it took to finish. I'll start. iMac 2.33Ghz Core 2 Duo with 2 GB of RAM. 100,000: 3.780 seconds 250,000: 24.110 seconds By the way, I got the same results with Safari running and with it not running, so don't bother closing it to increase performance.
