Here are some pictures. Loading the file took about 5 seconds (wich is about the avarage for opening a pdf file) and turning a page took (first to second page) about 1,3 seconds. Since it's a A4 document and you size it to about A5 you get a pretty small text size but I can still read it thought you might wanna use landscape mode.
Ow you'll have to take my word on the text readability because my webcam isn't that good
