Just a wild guess that I wanted to try myself but have not found time
for yet.

I read on c.l.p about psyco, that gives some speedups for python.
Perhaps someone could try 'psyco.bind' on the ZPT module. (Dunno if
this is possible even.)

It is supposed to work out of the box with ordinary python code, but
I don't know if the PageTemplates code can be classified as such.


Long shot indeed :-)
