Thank you for the reply.  I've tried several different things based on 
your suggestions.  Below are two with with comments on how each worked.

gs file.ps   # Slow page refresh.
gs -sDEVICE=x11   # Fast.  This is what gv used to be like.

If I run "gv file.ps" then:
address@hidden:~/bin$ ps xaww | grep gs
13079 pts/6    S+     0:01 gs -sDEVICE=x11 -dNOPAUSE -dQUIET -dSAFER 
-dFIXEDMEDIA -

The only option I haven't been able to figure out how to leave off is 
-dNOPAUSE.  The other options don't seem to have any affect on page 
refresh speed.
