Hi
My patches were supposed to make this work a bit better but there are
still some issues.
It looks like the patches didn't work for multi-page documents, but at
the moment it appears as if they are working if you have multiple
page-sequences. So if possible, try breaking your document into multiple
page-sequences and see if that helps.
Also, if you have references (e.g. page-number-citations) to pages a
long way ahead, this will consume a lot of memory. E.g. if you are using
page counting ("Page 1 of 2134") then that's gonna break things in
memory.
These problems are all solvable however the new FOP design is probably
the best place to solve them :)
I'm hoping to look at a couple of the problems some time soon but I'm
very busy with some other XML stuff at the moment. However, once that's
done I'll have some very good "real world" data to test the performance
of FOP with.
Note that I speak only for FOP, I haven't played with XSLT performance
yet.
Regards
Mark
