Red Hat Bugzilla – Bug 67576
Redhat 7.3: gv slow.
Last modified: 2014-03-16 22:28:23 EDT
Description of Problem:
gv runs quite slowly under Redhat 7.3, displaying text
a line at a time. It was much faster under 7.2 and prior.
Version-Release number of selected component (if applicable):
GNU Ghostscript 6.52 (2001-10-20)
Steps to Reproduce:
1. use gv to view the attached postscript file. (p1.ps).
2. compare the result with using gv p1.ps on Redhat 7.2 and prior.
gv displays the text very slowly.
gv displays much faster under Redhat 7.2 and prior.
I found that if i did 'gv -noantialias p1.ps', it displays much faster.
However, it doesn't look as good.
So something in the antialiasing appears to be making it run slowly.
The probelm appears to be in gv. gs p1.ps runs quickly.
The attached sample p1.ps is the first page from a technical report here.
Thanks for your help.

postscript file - first page from a technical report.
This seems to have been caused by a change in the file:
Find the line which reads:
GV.gsX11AlphaDevice: -dNOPLATFONTS -sDEVICE=x11 -dTextAlphaBits=4 -
and change it to:
GV.gsX11AlphaDevice: -dNOPLATFONTS -sDEVICE=x11alpha
This changes things back to how they were under 7.2 and makes gv fast again.
Yes, this is fixed in the beta gv.
