I assume that 'optimization' means to create a PDF file which is optimized for so-called "fast web view". If you click on a PDF file in your web browser, you certainly want that the PDF browser displays the first page before the whole document is downloaded. This can only work if the fonts used on the first page are not at the bottom of a PDF file. The PDF files created by pdftex are much smaller because subsets of fonts are created at the very end, when pdftex knows which glyphs are actually needed. A PDF file consists of many objects and the object table is also at the very end of the file. If you want to see the first page before the whole document exists on your machine, you have to make sure that the subsets of all the fonts used on page one are close to the content of page one in the PDF file. You also have to re-arrange the object table. And on page two, you certainlay need additional glyphs... The expression "optimized PDF" is certainly misleading, I prefer "linearized PDF" instead. A linearized PDF file is definitely not smaller than the original file.
