There are several issues here, as so often is the case
with performance questions.

4Suite simply is not designed for performance, from all
I know.  It's really quite slow, even compared to some
of the Java-oriented engines, whose advertising exceeds
their performance.

I have ideas about "quick fixes" that might work with
pyXML and 4Suite to accelerate their performance a great
deal.  They'd no longer be "pure Python" in the sense
they are today.  Yes, I agree that this appears to be an
area where C codings have jumped quite a bit ahead of
what's generally available in Python.

'Everyone aware of the new XSLT book from O'Reilly?  That
might palliate, at least, a bit of the sentiment about its
ugliness.
