[nylug-talk] Comparing RISC with CICS processor

[Paul Robbins]

Gary,
It really just comes down to what you are trying to do with the hardware. I
work for a retail chain which deploys 233MHz and 375MHz RISC systems.
Although this is some extremely antiquated hardware, it allows us the
performance we need.  The real key that we noticed with old RISC hardware
was upgrading RAM. The change in RAM makes a much more dramatic difference
for our application than a change in processor speed.

On that same note, I am trying to convince them to move away from AIX on the
RISC to Linux on an x86 box. In my initial R&D work (with a 1.5GHz PIII, i
think) is that the applications run much faster, but it is hard to make a
direct comparison since it is two difference OS's running on different
platforms.  If you are running Linux on PPC and are looking to move to an
intel or AMD box running an x86 version of Linux, I think again you are
going to find it hard to compare since the setup is so different.

I know this might just be random rambling, but if you want, i would be happy
to talk to you about the what I notice as the key difference in the
application processing for the two systems.
