Some things that I've done to speed up cfdocument requests are as follows:
* Check image links. Provide full URLs if possible. For some
reason if an image is not found, it takes forever to render and
display the little red x.
* Minimize the display portion. I usually put everything into a
cfsavecontent variable so all of my loops and things are generated
into a single variable (sometimes multiples) and I display just
one variable inside the cfdocument tag. This acts as a buffer and
seems to speed things up on my servers.
