Wendy's post about this suggests that she isn't having a problem with it (120 pages in 7 seconds).
To get a "sexy" looking grid on the page, with nice headers (multi-line, cell spaning stuff) we created our own TableRenderer based on iText's PdfPTableEvent - it handles drawing the headers and nice colored lines around all the cells. I think that slows it down quite a bit. As well as that, we wanted nice page headers and footers, with page numbering and ended up doing that through the PdfPageEvents. I think the combination of all that slows it down. Its probably not as bad as I think though - we currently generate a report by kicking of a batch script which starts up its own jvm and initializes a db framework - if I put it in a web app, that wouldn't happen every time, plus we could cache our report definitions - so maybe we would save a proportion of the 30 seconds. Thats next on my list after the current stuff I'm doing.
