[Wylug-help] Appalling Zope/Plone performance: what have I missed?

Is there anything in the Z2.log (Zope web server requests) or
the associated event.log?

I'm afraid I don't know where the Debian package hides these.

I think Zope is multithreaded, so the memory usage is misleading

I agree about the Plone documentation. I've found the source code more
informative than most of the docs, with the notable exceptions of.

* Andy McKays book at http://docs.neuroinf.de/PloneBook
* Upfront systems course at http://www.upfrontsystems.co.za/courses/plone/

The Zope API and ZPT docs from http://zope.org are also very helpful.
