If the PDF was generated by pdfTex on a Debian machine, the highest compression level (9) is already used. I don't know what happens when it's created via dvi->ps->pdf, and gs' documentation isn't clear about that, but ps2pdf14's pdf files are even slightly smaller (well, in a sample of two files...)
