I haven't used FOP with cocoon yet but I have with Oracle's XSQL server
pages. FOP is a very useful package but it is slow ESPECIALLY with tables. I
haven't looked to heavily into the status of the project for about a year
now but performance was a big issue with the dev team but changes weren't
happening too fast. I would read through their users list and see if you can
get some people to help you optimize your layout a little bit. There are
certain things that can be done other ways to save time.
