Hi all, I'm just collating some results from a test run I did using a Monte Carlo code on two different computers, one was a 1.5GHz P4 running Windows 2000 and the other was a 2.0GHz P4 running RH8. The Windows machine was faster than the RH machine. I ran the test again and got the same result. The difference was only 10%, but it was a surprise. Has anyone got any idea why there was so much of a difference? The test case didn't use much memory and the version of the program was the same in both cases (apart from running on different OSs of course).
