Yep that was the name of it. Turning slightly opptopic now :-)
On general computing a 2.8GHz Xeon were approx 1.5times faster than a 1.2GHz G4 powerbook. But with openssl the result were the opposite. The laptop were the fastest machine in the office!
This were also the reason why apple always claimed Photoshop were faster on mac than on windows. They found the most intensive plugin using altivec and compared those to windows.
It's cool. :) BTW, I found the following pages. it is a very interesting though it is a little old content.
