On one hand there is the wish to switch to PDF 1.5 to use
the more advanced compression feature \pdfobjcompresslevel,
then you want to reduce compression? For the final run I would
want to have \pdfcompresslevel=9. The previous runs can be done
using option -draftmode. That should be faster than any setting of

IMHO the alternatives are:

a) the current setting

b) the suggested new setting
   \pdfobjcompresslevel=2 (recommended setting from manual)

The whole issue would become less dramatical, if the format
generation would support a user configuration file, e.g.

%%% pdftexconfig.tex %%%
\openin0 pdftexconfig.cfg
\ifeof0 %
  \closein0 %
  \input pdftexconfig.cfg %   
%%% pdftexconfig.tex %%%

And pdftexconfig.cfg belongs to the user if he wants other default
