[Zope] Performance of webserver?

[Thaxter, Jason M.]

YMMV:

I've been working on benchmarking myself (freebsd/apache/pcgi/zope) and
noticed this:

	./start script uses the -D option.

I was noting rather high CPU usage.  I shut down Zope and restarted it with
	python z2.py -p/path/to/Zope.cgi

and got better results.  This allows the python process to detach from the
terminal, since -D is debugging mode.  

While many benchmarking stats are meaningless, I can support Amos' basic
contention that zerver is about 4x faster that apache/pcgi/zerver.
