  You are correct about the speed increase, a factor of 30 is possible
(but not common). I can't quite see you Dhrystone numbers for the 3100,
though. I got 24194 no registers, 26316 with. This is in line with all
other results I (and others at my site) got. Could you have used the
real time instead of the CPU and had a background load?
