Hi
The images alone take more than half a Gigabyte. I doubt you will find *any* FO processor which will work on this amount of data in a reasonable amount of time. You can try to resort to picewise generation of several PDF and try to get one of the general PDF tools to merge them without running out of memory. Don't expect Acrobat Reader to open the resulting file on a Windows machine with less than 2G memory.
I believe commercial FO processors and Acrobat both scale better than you think.
Using Ibex (from http://www.xmlpdf.com/ibex.html), and 3000 different 350K jpeg files, and a simple FO file which puts one image per page like this:
<fo:block>
<fo:external-graphic src="url('.\GUID-11.jpg')"/>
</fo:block>
<fo:block>
<fo:external-graphic src="url('.\GUID-12.jpg')"/>
</fo:block>It takes 9 minutes (with Java 1.4) to create the PDF file, which just over 1 GB in size. Memory used is less than 256 MB. The .NET version of Ibex takes only 5 minutes.
Acrobat will load the PDF and page through it using less than 160 K.
Both Ibex and Acrobat don't need to hold more than one image in memory at a time, so don't need to use lots of RAM. Even if you had ten images on each page, the document creation and viewing process would still scale very well.
