I don't think anyone has demonstrated any kind of symptoms of a
high-speed hardware fetish - rather the opposite in fact. The question
I asked was about how to *avoid* buying the latest and greatest
ultra-fast processor, but still effect a useful improvement.

Hmmm. For the money which I'm thinking of spending I could probably get
about 3 Pentium IV boxes. Then I could find somewhere to put them,
configure them all, maintain them all with updates, change my algorithms
to use multiple CPUs (in different boxes - not even SMP) and end up with
a solution which is slower, more power hungry, *much* noisier and rather
wasteful of time.

There comes a time when you just need to get some work done, and whilst
I plead guilty to having constructed multi-box processing networks in
the past, it only really comes into its own for a few very specialist
applications - and if I were going to do it I wouldn't use Pentium
IIIs/IVs these days. There's a big reason why Intel junked the Pentium
IV line; it was a developmental dead end.
