<pre>I had a look at that PDF and I fear that we have nobody who can help You with
it and pdftoppm in near futur: the PDF uses a lot of big stroke pathes and we
know that the splash backend and therefore pdftoppm has performance problems
with complex pathes.
But here at least some hints. The PDF has a very high metric (60 x 168 cm).
That results in a JPEG with a huge number of pixel and lines when You render it
with the default of 150 dpi. If You just need thumbnails, You can reduce the
render time dramatically if You reduce the resolution, i.e.
time ./utils/pdftoppm -png -cropbox -r 25 bug-poppler95362.pdf output/95362
real 32m38.676s
user 32m33.867s
sys 0m5.326s
Ok, nearly 33 minutes are also not such well but much better than over an hour.
And if all Your PDFs are such PDFs (like construction plans) You can think
about to use pdftocairo for Your purposes, which is also a poppler tool but
much faster with such kind of PDFs:
time ./utils/pdftocairo -jpeg -cropbox bug-poppler95362.pdf output/95362-cairo
real 2m13.642s
user 2m8.993s
sys 0m4.695s</pre>
