Yes, I found what you are talking about. Search for "do it." in title. 
Here is the excerpt from the message explaining how to get rid of ipv6 
module with one correction to reference the file "network" not the just 
the dir /etc/sysconfig Now when I select text in moz-mail I get minimal 
delay or pause.

On my system, /etc/sysconfig/network contains:
         $ cat /etc/sysconfig/network
         NETWORKING=yes
         HOSTNAME=amito.localdomain
but lsmod definitely shows that ipv6 *is* loaded.

I got rid of it by adding (as suggested in a later posting) the line:
	alias net-pf-10 off
to:
	/etc/modprobe.conf

I *strongly* recommend that you do this.  It speeds up web surfing by a
lot (probably because Doubleclick doesn't handle ipv6 properly), and
seems to speed up the system in general (though I can't even guess why.)
