If you have a large application, "Big Iron is your friend". But don't
assume that you need big iron until you have actually measured the
performance. SMP machines tend to have gobs of memory anyway.

It has been demonstrated many times. Pound exists for this very purpose,
and Zope introduced ZEO for the same reason. This seems like a very
shallow criticism, given that the problem has been solved many times
over.

I am in the process of setting it up right now, if anyone is interested.

I can afford to run bleeding edge, because I don't have any legacy to
support right now. (Some might argue that Apache 2.0 is not mature yet,
and may have unknown security issues.  I respond: Bind and Sendmail are
"mature", and certainly have known and unknown security issues. I would
rather take my chances with Apache 2.0, than with either of those. Yet
those same providers who refuse to use apache 2, continue happily
patching their BIND systems every other month.)
