It's amazing to see how putative minor changes affect pdf file sizes: The total size of the pdfs of our documentation (11108 pages in 47 pdfs) varies between 96MB and 306MB dependent on some minor changes in the our code and the ghostscript version used.

The good news: The winning solution (96MB)

  * is possible without PDFDontUseFontObjectNum
  * is possible with HEAD of git master of ghostscript.
