No, I just described the way we came to fastcgi and that it solved some 
of the Problems back than. 

I pretty sure that mod_proxy is much better than pcgi was. But logic 
tells me that it can't be better than fastcgi. Building a new connection 
costs time and CPU power and as the this connections have to be build
for each request the impact grows with the number of requets.

We are running zope 2.7.8 at the moment and working on mirgating to 
2.8.x at the moment exaly for this reasons.
