Windows 7 and multithreading = win

[frozenlead]

So I'm doing some work in Matlab on gravitational acceleration. I made a simple script that calculates the gravitational acceleration due to the sun and earth at distances relative to the earth for 10 million km off the surface. It's a pretty intensive calculation, and it takes a good 5 minutes or so for my notebook to finish (hardware in sig/config).

My roommate also made a similar script (to calculate the same result), and his is more efficient than mine, as it uses less conversion calculations for the distances. So, we decided to have a race. My slower CPU (he has a 2.53GHz core 2 duo mobile) and less efficient code running on Windows 7 x64, versus his faster CPU and code on Windows Vista x86. (We use the same version of Matlab)

My machine finished the code faster. In fact, we stopped his calculation, and his program wasn't even near 50% finished. I have to say, I'm pretty darn impressed.

Anyone else with nice multi-threading success stories?

xp vs win7

for a class i had to find the solutions to an infinitely recursive maze, i made it multi threaded to improve speed, computed much faster on win7 than XP (same computer)

That's not too surprising - XP wasn't that great at threading. Vista -> 7 just surprised me though.
