I think you're both right. We I benchmarked the Sun3 for engineering
type loads it was only a bit faster than the 11/780, certainly less
than 2:1. When I tested for text processing numbers were in the 2.5-3.2
range, and software development values were mostly between 2 and 3. My
impression is that the Dhrystone is more representative of an
engineering load.
