- Not to be disparaging, but "mHz" is "milliHertz" - "MHz" is "MegaHertz".
- If I was at DEC, I don't think I'd appreciate being told that my new
- machine runs a billion times slower than it really does. Of course if
- they could get 120 SPECmarks with a 7 second cycle time, that would be
- worth bragging about....
