Hi,
I just sent 25 requests using http_load to my public web server which runs
Plone 3.1.2
Zope 2.10.6
Python 2.4.4p6
on
OpenBSD 4.3 GENERIC#698 i386 AMD Athlon(tm) 64 X2 Dual Core Processor 6000+
("AuthenticAMD" 686-class, 1024KB L2 cache).
and got the following output from top.

1) I am using zeo and before setting up zeo with Plone 3.0.5 last year I did
notice a larger CPU usage
2) Plone and Zope were built from source using the same compiler flags as in
ports -- no major changes.
3) I have only Python 2.4.4p6 on the server and compiled everything that
required 2.5 to use 2.4. Previously, when I had both 2.4 and 2.5 running, I
had made mistakes with dependencies and that had caused some performance
problems.
Hope this helps.
Right now I am testing out Plone 3.1.5.1 with -current as of Aug 26, 2008
(Zope 2.10.6 with Python 2.4.4p7) and don't see high CPU there either.
So may be it is useful to test your site with newer versions of Plone and
Zope.
