Just a quick followup, by switching to Saxon we were able t

Hi
With my changes to FOP I can process tens of thousands of pages of
XML:FO in only a few Mb of heap. I have asked for testers but so far
noone has responded... this sounds like an ideal environment in which to
test, no? The performance of FOP seems also to have improved, probably
because th

xhtml->xsl-fo takes very short time say only fraction of total time. Thus it is best
done with external tool and not to load fop with it.

We did some playing around with a simple FOP servlet that does
XHTML->XSL-FO->PDF using Xalan and FOP and come away with the following
findings:
1. It uses quite a bit of memory. While running around 20-30 concurrent
users, each generating a set of four PDFs ranging from 2 to 5 pages five
times
