[Zope] Zope fine tuning HOW-TO / Zope Performance

[J. Atwood]

I used ApacheBench which is part of the default installation of Apache. It
is usually in /usr/sbin/ and is called "ab". The instructions are pretty
basic but you generally use the command:

/usr/bin/ab -c 25 -n 100 http://www.youzopesite.com

-c 25 is the concurrency level

-n 100 is the times.

So this would hit the server 100 times at a 25 concurrency level.

I ran tests of 25 / 100, 100 /100, 25/1000, 100/1000

I ran tests against just a DTML Document (static), a more complex one, pages
with one, two, three SQL calls. I also ran it against pages where I repeated
the same DTML over and over again (1, 2, 3, 10 times). I also tried
referencing images via <dtml-var image>, <img src=""> and finally by hosting
the images off of Apache and referencing them with <img src="http://...">.
Also increased and decreased the cache on SQL Methods as well as tried to
flush the Zope cache.

I also ran it against the same pages, images on an Apache installation on
the same box. 

That is a good place to start. I have all of my results in a big word
document that I will publish at some point, probably after repeating all of
the tests.
