Yes, it is. There are very few things I would say this about, but this is one
of 'em.
For a RHEL box to match the performance capabilities it would have to be
installed on Power as well (which it can be). I think the evidence I've seen
both in experience and raw numbers has shown the power boxes can sustain higher
levels of throughput and performance. Because to get an x86 box to perform at
those levels you would have to spend just as much, buying one really powerful
x86 box, or spreading it across multiple boxes.
All that said, if we didn't have a good AIX guy here, I'd go RHEL on multiple
boxes, or on a really powerful x86 box. I can admin AIX, but I'm much more
comfortable on Linux. So, as someone else said, it all depends on what you're
good at.

Subject: [ADSM-L] Check signals on Power vs. x86...
I'm looking around for an update on my expectations that power hardware
and AIX is more performant per memory/CPU/IO than x86 and RHEL.
I know this topic comes up from time to time; I don't think I've seen it
rehashed particularly recently.
I'm an advocate of AIX for this, but I wanted to check signals and
experiences, again.
