Ghostscript taking a lot of time for loading fonts while extracting text from postscript file
I want to extract the text of the first page (i.e., the cover) of the postscript file manual.ps.
For doing this, I am using the following command (the sed is necessary for removing the long spaces that I got on the output):
$ gs -q -sDEVICE=txtwrite -sOutputFile=- -dFirstPage=1 -dLastPage=1 -dNOPAUSE -dBATCH -dSAFER manual.ps | sed -e 's/ +/ /g' -e 's/^ *//'

This command takes 16 long seconds for running on this specific file, while it takes only 0.1s for other files. But the output I got is correct, it is actually the cover of the document:
Then, I removed the -q (quiet) option to see what is happening:
$ gs -sDEVICE=txtwrite -sOutputFile=- -dFirstPage=1 -dLastPage=1 -dNOPAUSE -dBATCH -dSAFER manual.ps | sed -e 's/ +/ /g' -e 's/^ *//'

Introduction
Troff and nroff are text processors that format [...]
This time, there are also fonts been loaded, but only before the output been written, and it takes only a tenth of a second.
So, how to get that first command run faster? Also, is it really necessary to load fonts for converting a .ps file into text? How can I optimize the gs command. And, most importantly, why this is happening only with manual.ps and not with all the other postscript files I have tried?
