Description Alex Cherepanov 2012-06-16 03:31:15 UTC 
gs takes 25 minutes to do
~/ghostpdl/gs/debugbin/gs -sDEVICE=bmp16m -o /dev/null Triptico-guifi1A.pdf

and 45 minutes to do
~/ghostpdl/gs/debugbin/gs -dNOPAUSE -dBATCH Triptico-guifi1A.pdf

With -dNOINTERPOLATE or -dNOTRANSPARENCY rendering time is within 1..2 sec
for any combination of devices and options.

The sample file has been attached by the user to the bug 693033, comment 2,
that is unrelated to the rendering problem.

I'm attaching the same file here.

Let me know if I can help in any other way

This file worked very fast (seconds) for me with gs 9.19, so maybe this problem was solved long ago.
Comment 3 Michael Vrhel 2017-01-20 14:21:09 UTC 
Confirmed it is fast now.
