I doubt. The facts posted by Raju for SGI machines seem more relevant.

Well I can't do that. I need helluva disk space to replicate the setup and I
don't possess that much space personally. My linux partition is barely 3.5GB.

Well, with latest reincarnation of one of the HP machine, I have gcc/g++ on HP-UX
too. I would like to put that for a test...

Well, actually reflection is a host of utilities. The automatic telnet is nothing
but 'rexec xterm'... :-)) But I agree, I should have been careful writing
that....

Surely. HP machine cost 10K$ and my machine is worth of 1.5K$. But there is
comparable magnitude of performance difference too. I would surely pay that much
if I feel that's worth of it..
These are rock solid machines. I don't mind OS running on top of that as long as
it's unix. I have (user) experience of HP machines. I am sure people from RISC
family of users would agree in general, be it IBM, SUN, SGI or alpha...

Well, to quote, 'Kernel compilation comes first in linux benchmarking' and I was
just identifying responsiveness of system under heavy loads. That's sure an
important parameter of benchmarking though not full benchmarking.
Besides being a full time tester these days, from my experience, companies do not
exist to carry tests. They do business in writing sophisticated and customised
test suites that sometimes compares with original software in volume...

Oh I didn't know that..
