snip - snip.

This is indeed very interesting.  I also had an impression that ZPT was
sometimes evaluating things that it did not need to in the presence
of conditional tags.

How does the timing compare with a Script Python and with an external 
method on your machine?

(Yes, I understand they are very different from ZPT and dtml, but I
think this might be useful information for a Zope architect. And this 
would give a common baseline.)
