[Zope] Zope is very slow!

[J. Atwood]

I have limited experience with ProxyPass. I have many Zope installations
(2.1.4, 2.1.6, 2.2.0b2, 2.2.0) on all sorts of different hardware
configurations (all RH Linux) and non of them are slow. Most are running
just plain ZServer but one (and the most hit) is running behind Apache with
Zope.cgi. I suggest trying that and seeing if it makes a difference.
