	Bollox does it ! Compare like against like (ie. K6 optimized on a K6 again
PII optimized on a PII) and then come back saying which is better. A K6
optimized app is always going to be better on a K6 then on an Intel chip,
just as a PII optimized app is always going to perform better on a PII than
any other chip. That's the point of optimization, it optimizes the code to
run the best on a given platform, you can't and shouldn't expect software
optimized for one specific platform to run equally efficiently on another,
different, platform.
