I downloaded and compiled poppler-0.28.0, and the pdftoppm speed is fine in 
that version, the same as in the old version I've been using - 0.20.5.

It seems that some change between 0.28.0 and 0.29.0 is causing a 6x slowdown in 
pdftoppm, at least in the test cases I'm using...

Hi, I'm upgrading my copy of poppler for the first time in a while, I've been 
using 0.20.5 but now I've downloaded 0.29.0 and I'm finding
that pdftoppm is *much* slower under the new version, maybe 5x or 6x slower.

Is this already known, and for a good reason? Sorry if this is already 
understood.

I'm using a recent centos 6, 64 bit linux and the following configure command:

./configure --prefix=/usr/local --disable-libjpeg --disable-libopenjpeg

forcing poppler to use the builtin jpeg library. This is the same config as for 
the old version I have (0.20.5).
