Why is the XSL-FO to PDF step so slow!
Layout is a hard problem.
We are talking about only two pages of PDF output. I must admit that
those two pages contain a hell of a lot of complex tables. Is that the
problem?
Is there any way to speed up to XSL-FO to PDF step?
1) Would a commercial FO-processor help me out?
2) Is there any tutorial around for how to optimize the FO
conversion speed?
So far as I know, the only rule is "don't specify anything you don't
have to specify". It's otherwise difficult to optimize FO processing --
the actual layout step -- because there may be only one way to express
what you want to see, and the whole point is a particular layout.
Commercial FO-processors are faster, but not eye-blink fast. Layout,
especially of complex tables, goes off into the land of seriously
polynomial time very easily. I used to treat a second per page as an
acceptable number when dealing with substantial index documents.
