Don't take too much account of this: it's not representative unless you include illustrations that must be rendered on the fly in your books. Page 2 has two of them (figure 1b and 1c): even on a pretty fast system that page feels slow. Other illustrations in the paper seem to be bitmaps, though, so page 2 is certainly worst case. (I think I find image masks in here as well: that almost certainly adds to processing time, especially if you remember that the iLiad does not have a FPP unit.)

The document is also unusual in that I count 22 typefaces in 10 A4 pages ...
I can't say for certain how much that does, but it is probably going to stress the font bitmap cache a bit -- though page 2 is hardly exceptional here.

Pre-rendering will improve speed for this document, no doubt about that. But I don't really think the document is representative for most iLiad users.
But it is a pretty good illustration that special care has to be taken in preparing iLiad versions of PDF documents.
