Created attachment 11405
Original djvu file

While investgating the problem of evince taking an hour and twenty
minutes to print the attached djvu file, it was discovered that if it is
printed to a PS file it prints quite quickly, but then using ps2pdf to
convert the .ps file to a .pdf file takes 1 hour and 17 minutes.

Running the "top" command while the ps2pdf conversion is in progress
shows that gs from the ubuntu USER is at the top of the list with 100%
use of one of my four CPU cores (single CPU state/separate CPU states
can be toggled by pressing "1" while top is running). SHaRed memory was
fixed at 3776 KiB, while VIRTual memory size and RESident memory size
steadily increased to over 100000 KiB each after 10 minutes and
continued to steadily increase to over 200000 KiB before the conversion
completed after 1 hour and 17 minutes.

Unless I am mistaken, gs is ghostscript.This occurs on Ubuntu 14.04
"Trusty Tahr" with ghostscript 9.10~dfsg-0ubuntu10.2 and on Ubuntu 14.10
"Vivid Vervet" with ghostscript 9.14~dfsg-0ubuntu4.

The resulting .PS file is too big to attach here, so you will have to
generate it using Evince.

Some further comments by Till Kamppeter:

"Sending the PostScript file directly to a native PostScript printer, for
example using the command

nc -w1 <IP address of printer> 9100 < Grammar\ 4.ps

leads to a printout in a reasonable time (2-3 pages quickly one after
each other, then 5 seconds pause, 2-3 pages again and so forth).

This means that the PostScript file produced by evince is awkward, but
GhostScript is really TOO slow, meaning that there is room for
improvement/fixing in Ghostscript.

Independent of this, the djvu software used by evince needs improvement,
too, first it should generate better, easier to process PostScript, and
second it should be able to directly convert djvu into PDF, as PDF is
THE standard format for printable documents under all operating systems
(please consider reporting an upstream bug here, too."

We need either a PS file or a PDF file. This file type is not supported.

If you can't make the PS file you test with available, we will have to close
this as INVALID.
