Hi,

Carlos Garcia Campos of GNOME team (carlosgc at gnome.org), suggested I file a bug
report here instead. The original bug report is here:

My original post:

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

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.
