I've had a similar experience when I made a poster (using "poster") and the PDF made from the poster.ps was _smaller_ (about 4 times IIRC) than the source PDF even though "poster" simply copies the input PS file 4 times into the output file, so I expected the file size to grow by factor 4. gs seems to do a pretty good job at converting PS to PDF!
