OK, you're right, there is a problem here. I note that the PDF 1.3 spec,
with 518 pages, is 5 MB; the EJB 2.0 PD 2 spec with 554 pages is 2.8 MB, the
SWI Prolog 3.4 reference manual, with 222 pages, is ~1 MB, and the Java
language spec, with 852 pages, is ~3.5 MB. Our very own XSL spec is 5.3 MB
at 406 pages (the RenderX version).
The documents cited come in at 9880, 5180, 4610, 4210 and 13370 bytes per
page. Illustrations, whitespace and font size make quite a difference,
obviously, to +/-100% at least. You are saying that you see page averages of
about 50K, or on the order of 5 times these examples.
Can you do some basic stats, maybe with a text editor and/or simple scripts?
Where is all that size being taken up? Is the trailer huge? Are the
individual pages themselves taking up most of that? If so, why? What is the
difference between your typical page, from FOP, and a page in one of these
other documents?
I don't produce monster files, and certainly for my test docs I manage to
keep per page sizes comfortably below 5K, so it would be interesting to see
if there is some kind of overhead that we can whittle down, that I just do
not see.
