Good morning all,
I work for the City of Largo, Florida and we are trying to get the last push to go live with an OpenSuse 11.4 server and the GNOME desktop. Unfortunately we seem to have a low level problem that is keeping that from happening. I mentioned some of it on a recent blog post:
http://davelargo.blogspot.com/2011/08/opensuse-114-woes.html
The server seems to have some kind of scheduling problem and acts like a machine that is swapping, yet nothing is showing up on top and we appear to have plenty of memory. Even local disk access is slow, and the networking layer is showing lots of packets being lost.
When I have about 10 users on, the machine is very fast and works as expected. When I get to about 40, it has a huge slowdown and runs poorly. With 40 users on, when I "vi /etc/hosts" it sits and blinks for 3 seconds before the file appears. Navigation is sluggish.
An older server with older OpenSuse can run 200 users easily with no performance problems.
The blog comments had a few tips, which I have tried with no changes in performance. It just really feels like a low level bug/problem that is not fixable by me by settings or tuning. Top shows plenty of CPU and RAM.
If anyone wants to email me with tips or chat with me on the IRC, I'm logged in as dave_largo.
I noticed that some newer kernels (3.0.1) are in the experimental channels, if that will resolve my issues I can certainly try and upgrade.
Current kernel is:
kernel-desktop-2.6.37.6-0.5.1.x86_64
Thanks in advance, right now I'm completely at a road block.

the latest updated kernel for 11.4 is 2.6.37.6-0.7 I saw you use the -desktop flavor. If it's serve as server I would propose to give a try to the -default flavor. If you activate the multi-version in zypp.conf it's easy to have the two installed, and safe.
openSUSE -desktop flavor seems to have some perf tuning to be more reactive but for typical desktop usage.
I'd suggest this too. The -desktop flavor is preemptible to try to provide low latency and this is often at the cost of throughput. You still shouldn't be seeing packet loss, though. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk5NRP4ACgkQLPWxlyuTD7LmoQCgpWfCSfAr01pQVcQbwWrZIElW Sv4An3WvzjeoH6/7Jb/LDl/fVAMazrQe =oASu -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
