I have found one partial solution. I say partial as it shrinks the PDF
to about 2/3 the size, which is still much larger than people achieve
with Adobe's software.
1) Export as an EPS file - this makes a massive 18 GB file for the
above example
2) Use the tool ps2pdf which uses Ghostscript.
I would add, this was done on Mathematica 6.0.2 on a machine running
Solaris x86, on an Intel CPU. This involved the modifications (posted
on here some time back) to run on an Intel CPU. However, I very much
doubt this would change the result. But running ps2pdf on Windows
Linux or Mac might well give differerate results.
