11.2rc and poor internet performance

dual booting 11.1 and 11.2 x64 kde4.3 and 11.2's
browsing performance is horrid vrs 11.1's.

Seeing Opera state "sending request" for 5 seconds
before anything starts dl'ing and the dl's are also
much slower and Chromium is no better.

11.1 and 11.2 has networking configured the same
(from what I can tell) and I switched 11.2 between
networkmanager and ifup with no discernible
difference. Both 11.1 and 11.2 have ipv6 enabled
and turning off in 11.2 made no diff.

any ideas?

I recall reading a bug report that turning off ipv6 on 11.2 in fact did not turn off ipv6. On my Sandbox PC I was able to turn off ipv6 on 11.2 by simply selecting the disable ipv6 upon install. That purportedly DOES work.

yes - seems that ipv6 was the cause though it
worked fine in 11.1 and was disabled in yast
(though as reported above not really)

and will quote the solution given:

"2) KDE 4.3 and others problems with FTP
Reason was very simple - IPv6. it was used in
name resolution by KDE libraries.
To disable IPv6 for KDE place following:

export KDE_NO_IPV6=true

in your "/etc/bash.bashrc.local" and restart KDE
(+ may be kdm, so if you dont know how to do that
- just reboot)
If that does not help - we have to disable IPv6
completely (in my case IPv6 is useless, so I can
disable it with no doubt)
Forget all stories about disabling IPv6 in
/etc/modprobe.d
IPv6 now compiled into a kernel and no longer a
module, so /etc/modprobe.d configuration wouldn't
help.

Just try to do following (as root) (and don't
forget to replace "eth0" with name of your
network interface) :

sysctl -w net.ipv6.conf.all.disable_ipv6=1
ifdown eth0
ifup eth0
ifconfig | grep inet6

If output of grep is empty - you've successfully
disabled IPv6. It will be disabled until you
reboot. To disable IPv6 permanently add a line to
/etc/sysctl.conf:

net.ipv6.conf.all.disable_ipv6 = 1

reboot and enjoy an OpenSuse 11.2 without
mysterious network problems."

I use this and it works perfectly for me:

Append ipv6.disable=1 to your boot parameter either by using yast or edit /boot/grub/menu.lst manually

It's not encouraging for others to install openSUSE-11.2

Hope,it will be fixed before final release.

I think this needs to be put in context. This ipv6 problem does not occur for the majority. In my case, I typically select to disable ipv6 as one of the installation options. And even when I have forgotton, I have not had an ipv6 problem.

Possibly, but I suspect it will NOT change between RC2 and GM version. Only really blocking problems are fixed between RC2 and GM versions. Hence the work arounds noted in this thread are good to keep in mind for the minority of users who might encounter this anomaly.

You guys are awesome! Disabling IP 6 (boot opt) did it for me. I'm completely new to Suse (from Mandriva, Ubuntu), and was so disapointed looking at a nice OS with lot of troubles with the internet connection(s).

My Opera was not just working bad before disabling: it hanged, took all CPU power.
