I think you are referring to the data that I posted for my Athlon II x4 system, but that is *NOT* what the data showed. I thought that the data clearly showed pretty good scaling up to 4 processors, so I don't know what you are seeing that everybody else is missing. I will copy some of the data below, but basically it showed that total time almost cut in half when it went from 1 to 2 processors, and again when it went from 2 to 4 processors.
