Small file with several pages to flick through

Evince is extremely slow on some files, especially if it contains images or
graphs.
I'm running Ubuntu 14.04 (libpoppler 0.24.5-2ubuntu, but it also affects Ubuntu
14.10 with libpoppler0.26.5). In earlier versions, the test pdf attached would
render each page almost instantaneously, it now takes several seconds per page.
Even Firefox (with the built-in PDF renderer, HTML5) can render this much more
quickly.
In order to test this, it is not enough to look at a single page, but you need
to quickly flick through several pages. Note that the file itself is pretty
light.
I'm using Sandybridge integarted graphics, i5-2450M.
