Hi Max,
I see now what you mean.  The problem here is that pdftex creates
subsets of all fonts used on a particular page before the output
routine is called.

I've extracted all 1323 pages from the original file and creted a new
one.  It took 40 min.  The size if the new file is 199 MB.

  $ pdffonts mypgfmanual.pdf | wc -l
  9845

So I suppose that font subsetting takes most of the time.  

To confirm this, just try with one of the PDF files at

  https://tug.org/~kotucha/photos 

They do not contain any text and you can process abt. 14 pages per
second.   They were created with pdftex of course.

Regards,
  Reinhard
