Certain PDFs opened in Evince or Atril using the Poppler backend are extremely slow to render, to the point of being unusable. This is on a very fast Thinkpad laptop with a quad-core processor and an SSD. The same PDFs render instantly using a Windows PDF reader (http://www.tracker-software.com/product/pdf-xchange-viewer) (running under Wine!!).
This file is only about 2MB, but it takes many seconds to render each page:
On the other hand, some long, complex PDFs with images render quickly with Poppler, like this one:
Thanks for looking into this.
Reference bug #91248
This one may be hitting a particulary slow spot in the cairo renderer since page 3 takes 500 ms to render in Splash and 1800 ms to render in Cairo.
Assigning to Cairo since there's probably something to improve here.
