One of the best performance charts I have ever seen is in "Programming
They show a TRS-80 and a DEC Alpha doing the same job, but the TRS-80
code is better written.
The DEC is hundreds of times faster... until the problem size
increases to a point at which the DEC would take 400 years to do what
the TRS-80 does in fifteen minutes.
Excellent example of how little raw power means if you use it wrong,
and exactly why throwing horsepower or misguided ideology at a problem
Programmers do *NOT* always cost more than computers.
