Bogomips are calculated by simple executing an empty loop. So it has no
real meaning in terms of processor speed. That`s why they are called bogo!
The K6 processors are heavily optimized on integer calculations, thats
why they get such good results in the comparisons with Intel. Especially
in Windows test suits. The Pentium Pros and Pentium II have much better
floating point units.
