Circles are cool. I often feel like I'm running around inside one.
I found a small Pi calculator that uses a random number generator to demonstrate the Monte Carlo method. It's just for demonstration purposes, and it's not cross platform, but I imagine it demonstrates an important aspect of the emulated CPU numerical power. http://homepage.mac.com/alk/picalculator.html
At the bottom of the page are three versions, one for 68k processors, one for PowerPC with OS 7 to OS 9, and the third for OSX.
I ran both the OSX version in PearPC/OSX 10.3.5 and the 68K version in Basilisk OS 8.1.
I set the counter to 2000 iterations, with the check boxes as shown in the screenshot. The time to complete was 76 seconds.
The same run in Basilisk/OS 8.1 (2000 iterations) took only 8 seconds.
Unfortunately there's no exact windows equivalent that I could find, so I can't tell how much of a slowdown there is compared to the host.
I have asked some people to give me an idea of where PearPC falls in terms of performance relative to other macs. So far I have one result, a G3 450 that turned in a time of 7.2 seconds for a 2000 iteration run.
That gives my PearPC about a [b:3698ddd7a6]10.5X[/b:3698ddd7a6] slowdown compared to a G3 450.
