Regardless of the contents of your document, you may want to process the 
resulting PDF file using the "Multivalent" compress tool before shipping 
it, cf. http://multivalent.sourceforge.net/

Using Heiko Oberdiek's minimal example, pdfTeX-1.40.4 produces a file 
with 5490 bytes;  the Multivalent compressor outputs a file with 5164 
bytes (5% smaller).  When run against a more realistic example (13 pages 
containing some equations, using times.sty), it saved as much as 23%. :)

Ad astra, Markus
