You may already be aware of this, but the rendering speed is exceptionally slow with documents from Internet Archive:

http://archive.org/details/lifewritingsofth01pain

This contrasts sharply with most other PDFs, including some pretty high-rez ones, which render either really fast or acceptably fast with Evince.

I think the problem is not specific to any version of Evince. I am using version 3.4 on Ubuntu 12.04, but I have been experiencing this issue since the first version of Evince that became default with GNOME on Ubuntu. I always expected this would go away in the next version, assuming that since speed was generally good, this was just of problem of "compatibility" with certain PDF (possibly buggy or non-standard) generators.

The Properties box of Evince tells us that Internet Archive PDFs are:

- Recoded by LuraDocument PDF v2.28
- PDF version 1.5
- Optimized

I think there must be something in those PDFs that is not handled correctly by Evince.

Pages of those pdfs are high resolution images, it's not very fast to render, but I don't think it's a disaster, every page is rendered in around 1 second for me using poppler from current git master and cairo 1.12.2. In any case, slow rendering is usually a poppler bug, so if it's still very slow to render for you with current poppler, file a bug report in freedesktop bugzilla. 

Thanks for reporting.
