If you had lots of graphics, knocking it down from 1200 to 600 would produce
a large reduction. I wouldn't reduce it any further, however

It would be interesting for us all to know how much each of those things 
you changed (i.e., changing from 1200 to 600 dpi, turning on graphic 
compression, saving out of Acrobat with Optimize turned on) contributed 
individually to the total file size reduction.

I recently produced 57,000+ PDF pages (in 31 files) for a client, splitting 
them into three groups for zipping. The total size of the 3 zipfiles was 
"only" 52 megabytes,
or about 0.912 megabytes per 1000 pages. Since the whole set of files had 
to be ftp'd to the printing company, the drastic reductions, particularly 
the large reductions in file size achieved by batch-optimizing the 
Distiller PDFs in Acrobat, reduced the upload time to something that was 
tolerable.The whole job from start-to-finish (not including upload time) 
was done in about 50 hours. That included the following steps:
1. Database publishing using UniMerge to merge the database records with a 
FrameMaker merging template to produce FrameMaker output files.
2. Producing postscript files from FrameMaker book files.
3. Distilling the postscript using Distiller 4.05a.
4. Batch-optimizing the PDFs with Acrobat 4.05a.
Most of the time was spent in generating the postscript files from 
FrameMaker  book files containing an average of 1838 pages each, which 
typically required about 40 minutes on a 400 MHz Pentium Win 98 platform 
with 128 MB of memory.
