- Not really. For example on superscalar processors (SPARC) this isn't a good
- test, either.
-
- [some good comments which I can agree with deleted...]
-
- One thing I will never understand:
- People tend to "measure" their cars in terms of horsepower and speed,
- their houses in squaremeters, their girlfriends in (...) ... and
- finally their computers in terms of "MIPS".
-
- As a statistican once said: "We don't know what to measure and why --
- but we do a damn good job on it!"
-
- But "performance" and "usability" is a much more complex topic.
- Terms as functionality, integrity, robustness and psychologic
- impacts are MUCH more relevant to it as any speed. For example I work
- MUCH more productive (objectively) on my NeXT as I do on a big MVS
- system or even a DEC. (Though they are much "faster") Of course
- sometimes I am waiting for my NeXT (at the moment my swapfile is about
- 60 MByte big) and some jobs require a higher speed (Mathematica,
- rendering and some other jobs) -- but who of us really needs that?
-
- Most of the time my system is waiting for me -- not vice versa.
-
- You always need the right tool for the right purpose. Same with cars. A
- friend drives a Porsche 928 Cabrio -- quite fast car with many HP -- but
- once you had to sit in the back you start hating it. No family car. (And
- in the US you couldn't even drive it fast...)
-
- Just my impression, Gerhard.
