well, CPU-Performance is not everything. Its always a question about the
whole system (and application behavior). If you need pure CPU-Power then IBM
z/Series would be the wrong choice. But most of the systems don't have
permanent a cpu high load. If you need availability and scalability
(on-demand freatures), then you more on the right path with the z/Series.
But Linux needs for that dynamic reconfiguration tools ! (like dynamic
memory,cpu attach and detach) 
On the other hand, my experience is that many of the projects take a look on
the coast side (with a very partial focus) and nothing else...and that's the
fault of the sales people. They sell systems and later on a very clever guy
is coming with the consolidation idear. But in the meanwhile every little
server is so special in his application behavior and SLA's that nobody takes
the coast of the consolidation. Hypothetical consolidation is a big word, 
practical it's a lot of work and also cost intensiv then. Clever people may
think about a long term strategy and then z/Series would be more
cost-effective.

My answer was, and still is (and likely always will be) avoid any
application that is CPU intensive.  Yes, the zSeries has gotten faster, but
so has Intel.  The price-performance curve for CPU intensive work still
favors Intel.  I've seen nothing in the IBM announcements that would lead me
to change any of the recommendations I've been making for the last 3 years.
Unless and until the price-performance curve for zSeries matches that of
Intel (or comes a couple of orders of magnitude closer), I will continue to
make the same recommendations.

-snip-
Linux on all sorts of platforms was just a gleam in
someone's eye 5 years ago.  It started getting pushed
on the zSeries 3 years ago and the software and
hardware have made great strides in the last 3 years.

So CGI may not be appropriate today. So what is there
we said was not appropriate 2 or 3 years ago that may
be appropriate today on Linux zSeries?
