Bottomline....it just doesn't scale. A simple 3 page test give me throughput so bad i can't speak of. Zope didn't scale...hence i tried Zeo/Zope....that didn't scale too(On the same machine). Am trying Zope/Zeo across machines now and will let you know about the results. Apache+Zope is something i havent looked at yet.

You must be doing *something* wrong.

Man have I been there. I spent a bunch of time trying to understand why my (Plone) site was not getting cached properly. No matter what I did, performance was awful. There turned out to be several different issues all confusing each other. In my case, one of those issues turned out to be the fact that the accelerated HTTP cache manager had a line comment out of it in Zope 2.7.0 that caused me quite a bit of grief (see http://collector.zope.org/Zope/1345). That seemed to make a big difference for me (but I'm running Plone over Zope and Squid instead of Apache). This probably doesn't help with the main topic of this thread, I just wanted to empathize with Trevor. :-)
