If you think that is slow, wait till you try Apache's FOP.  It's been a
while, but IIRC, when my reports went five pages or more, I believe it took
around 30 secs.  With 50 pages, my users started calling and asking if the
app was still running.

My current users are Excel lovers, so I generate formatted Excel docs
(through POI) that they can edit or print directly.

I was gonna use IText the next time I needed PDFs.  If that's slow too, are
there other alternatives?

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.
