That is because there is no high level framework with servlets.  There
is no standard authentication framework, acquisition framework, standard
object/relational model, template language, through the web managment
system, object publishing over multiple protocols... servlets don't come
with an HTTP, FTP, PCGI and a FastCGI server.  All of this you get with
Zope out of the box.

It may very well be.  With the subsequent open sourcing of ZEO however,
you could scale your Zope application invisibly to a hundred machines,
how far can  you scale that Servlet without making any changes to it at
all (or not paying money)?  Requests per second is only one tiny factor
of scale, and when you scale beyond a handful of machines it becomes
less and less important.
