Good to know.
I wanted to make the test myself though.
There's one / two modules where I would expect an increase in
performance. The rest of the application will rather definitely not
benefit from psyco.

Also one thing, that I wanted to try is  to not use psyco for the
application itself, but just for running py2exe a little faster.

Well many module depenencies. :-( and also a lot of old legacy code,
which will probably not survive PyPy (files not being closed explicitely
for example)
