I'd bet a fast SD card will make the reader faster when you first put the card in and the metadata loads, but for turning pages it shouldn't really matter. It also shouldn't matter how many pages the doc has when turning them (only initial load).

The time it takes to read even an enormous 1MB pdf page from a slow 8mbps sd card is still... 1 second. The biggest bottleneck is in processing the pdf pages and all their rendering directives and parameters. It shouldn't happen to an image-based pdf, however. Hmm... I wonder if there's other useless crap embedded in it as well. If you have Adobe Acrobat, you can try going to Advanced > PDF Optimizer and dumping as much junk as possible.

Also, if page turn speed is that important to you, you can try my PDFrasterFarian script which renders pdfs into image-based BBeB books. Page turns are then about 2s incl. eink.
