Steve,

On the Mac I do

	brew install --cask pdf-squeezer

works well, and so I bought the license.  Comes even with a command line
utility so it went straight into the Makefile :-)-O

I must confess, I have a 3.9 MB accounting software of which I only need
the installation part which is 6 pages, so I use qpdf to pull out those,
making 75K.

	 brew install qpdf

Besides not having answered (timed) how long it takes, I would
personally, besides looking at shrinkers, int he first instance look at
how the sucker is generated and work on that.

I save my images on R with ggplot2::ggsave and the help page shows:

	device	Device to use. Can either be a device function (e.g. png),
		or one of "eps", "ps", "tex" (pictex), "pdf", "jpeg",
		"tiff", "png", "bmp", "svg" or "wmf" (windows only).

I however, put the R chunks into my LyX files so that the images are
generated on the fly (knitR).

You asked in another message how many words my handbook has.  It has 25
child documents and I don't know how to run the stats from the comand
line, but the result has 950 pages. As I wrote elsewhere when working
on a chapter I can compile that child document separately which takes
5-10 seconds and look at that before running the Makefile. Works for me.

greetings, el
