It usually depends on what is in the PDF and how it was created. I saw the worst performance/bloat when images were not all the same format and/or orientation, and DOCX/PPT/PDF. If you have time, pick it apart. Make all the images the same type/DPI/resolution/orientation/compression. Rebuild and export so you aren't saving a bunch of undo actions and different formatting styles.
