How many Zope threads were running at the time?  This is an obvious
tweak.  You wouldn't slam Apache with 200 concurrent requests when
'MaxClients' was set to 5.

Also, how realistic is that dataset?  Sure it lets you flex the muscle a
bit, but I suspect your full dynamic path involves alot of other systems
too, like relational database.

Keep in mind also that Zope is a dynamic system which is, by concept,
slower than static systems like Apache.  Apache is also written in C,
most of Zope is written in Python.  Python is an awesome language, and
zope in infinitly extensable, but the cost of this extensability is
bytecode interpreter overhead.  Many parts of zope are written in C for
the reason of speed.

If you compared Zope's speed to other fully featured applications
servers, I think you'd be surprised at how fast it really is.

Both.

Not supported.  I don't know if anyone is developing (I think someone
is).
