Dear all,
I am having, unfortunately quite sluggish performance in my opensuse 12.1 . For example it takes two secons when you click the back button on konqueror to move you back, or two seconds in Konsole (kde) to make a new tab.
I have tried to see if there is a process eating the processor but unfortunately I have not spooted something with ksysguard or top.
So there might things causing that performance i.e something blocking i/o.
I would like then to report yo uthe following but I am not sure how to find them
Graphic card used and driver
Active repositories
Software installed
Background processes running.
Could you please help me on how I can gather this information for helping me improve my system’s performance?
I would like to thank you in advance for your help
If you have kde there should be a “sysinfo” under the computer section of the menu. It should list a lot of information there. Also helpful is to know if your gpu has 3d acceleration. You can find this out by running this from a terminal:
glxinfo | grep direct
zypper lr -pu
Not sure what would be useful unless you have not installed any buggy (3rd party) software out of the suse repositories.
Try the command: **top
**
Also note you might try to disable desktop effects or also switch your system’s qt to using raster with this program: software.opensuse.org:

there is a ‘thing’ which crawls through all your disk collecting info to
aid you in searching your disk(s)…if you have recently installed
openSUSE but have a goodly amount of photos, movies, music, etc etc on
your system it can take a LONG time to get that collecting info job
done…for two reasons:
it takes a long time to do the job, and
it will take even longer because the ‘crawler’ automatically gives way
to other system needs…like if you are reading a web page and making
no input for a few seconds the ‘crawler’ will automatically go to work
searching and cataloging your ‘stuff’ to a database…but, if while it
is working you click back in Konqueror (or make any other demand on
the system), the crawler will be in the midst of HOGGING your system,
but it will let go of the system resources and stop working…
and, that transition might be the delay you see…
so, if your install a relatively new one and you want your stuff
cataloged for a faster search: just put up with the delay until
everything is in the DB and it should get snappier…
personally, i killed the crawler…ask, and someone can tell you how…
or, if your (say) a week or two old, then i ask if this delay is only
seen during the first 30 minutes to an hour after boot, but then goes away…
or, are any of your disks are on other machines and you access them via
a network…
and, tell us which version of KDE you use, please…and your four questions:
click on the “My Computer” icon
type this command into a terminal:
zypper lr -d
then copy/paste the in/output back to this thread using the instructions
here: http://goo.gl/i3wnr
3. i don’t think we want that just now…anyway the list is VERY long
(but the rpm command, with the correct switches gets it)
4. same as 3 (but the ps command, with the correct switches get it)
It has been reported that if you run the Dolphin file manager in Super User mode several times that the usage of dbus-launch can have an adverse effect on your system operation. You can edit the Dolphin Super User menu entry and remove the dbus-launch command and extra space and it will still work as required. This problem can effect anything that uses the dbus-launch command. If you need to edit a system file as root I have two bash scripts that can help.
Its all just a guess and not using the proprietary video driver (meaning you are using the open source one) can slow you down, but this is not a recent issue at all but has existed for a very long time.
and the processor seems to be always less than 40% (not any heavy process running except windows waiting for me, like firefox)
I am running a lot of firefoxes. One windows per virtual desktop and each window has 5-6 tabs.
In the past I was thinking that the flash plugin must be the problem but I can not see it consuming any cpu and firefox flash does not work at all (usually I open opera for some flash video)
The problem seems to be somewhere in the i/o procedure. Typically the slugglish performance is not constant but it comes and goes. When this happens it takes 5 secs to switch a tab in firefox (always there is memory). When you try to write a text the text appears after 5 secs (even in very busy cpu states one can write text at the same time). Even the cursor when clicks inside a text editor nees 5 secs to change from normal pointer to enter text pointer.
It might be also something with my video drivers. Need help to check that
Just as a clarification, if you do remove the “dbus-launch” from the Dolphin Super User menu entry, you need to replace it with “kdesu …”, otherwise you will just end up running Dolphin as a regular user.
Actually that is not so, at least on my system as the **Run as different user **is set (on the Advanced User Tab) for Dolphin File Manager - Super User Mode. Even though the user name is blank, it still requests the root user password and operates just as before but without the dbus-launch command.
If you go through several messages each day, try to give some help as you can, it is amazing how much you can pick up on using openSUSE and Linux. I get new things all the time I can use in openSUSE. Even if I can’t use it now, I save everything of interest I find as text files for each subject. Then, sure enough later, either I need it or some one else needs it that is asking for help. And, you learn things from new and seasoned users all of the time. I think it has to do with each user point of view as to what they pick up or not. I might say in a message that something can’t be done and a newbie comes along and says it ain’t so. It happens more than you can imagine. So, I suggest for anything that sounds useful, make a note of it. Cause later, you will discover that you need it and/or you have forgot how to do it.
(notice in this one that even the full utilization is at 51% the process list utilization does not give 51 if they are sum up 12+5+4+1+1+1+1=25) http://paste.opensuse.org/images/85456707.jpeg
Looking at the CPU (History) usage chart alaios shows me a very busy computer. The only time I get utilization like that is when I am compiling a kernel. Seeing systemd at 12 % seems very odd as well and makes me wonder what is it doing so high after the system has already started up? I can see that your computer is busy and and should be very sluggish. You seem to have a humungous SWAP at 50 GiB, is that correct? You can not really need more than 8 GB in my opinion and don’t seem to be using any at the moment. Main memory seems OK as well. But system usage tells me a lot of somethings are running on your PC, but what is it? I guess I remember you saying you had eight virtual sessions. What is the makeup of the applications running in this configuration?
Virtual Desktop 1:
-Firefox with 6 tabs opened
-One konsole with 3 tabs (one of tabs has remote ssh connection active. Just the prompt there. Nothing running)
-JabRef
-Dolphin showing an image folder (image previews could be also seen)
Virtual Desktop 2:
-Thunderbird (main window)
-Thunderbird (reply to email opened window)
-small dictionary program
Virtual Desktop 3:
-Empty
Virtual Desktop 4:
-Firefox with 16 open tabs
-kwrite containing unsaved text
Virtual Desktop 5:
-Konsole with three open tabs
- Dolphin just one window (showing my home folder)
-Konqueror with two open tabs (both showing over fish (ssh) the contents of remote folders)
Virtual Desktop 6:
- Firefox with 4 open tabs
-Konsole with one tab
-System monitor window (ksysguard)
-Dolphin showing contents of local folder
-ksnapshot
-vlc
Virtual Desktop 7:
-Firefox with 7 opened tabs
-Konsole with 5 opened tabs. All running ssh sessions to remote host and 4 of them running inside that remote shell R in command line mode
-5 kwrites (3 of them are through ssh -X port forwarding connection from remote server)
-konqueror with 2 opened tabs to remote host (With fish)
-okular . 4 instances with loaded pdf files
-2 open thunderbird windows ( I have loaded two email answers and moved them from desktop 2 to this one)
My processor is a Intel Core 2 Quad CPU (8400 @ 2.66)
Of course you might tell me that I have left many windows open around (but as I have seen that I am not running low on memory I thought that would not be too bad to leave them open). So if some of the programs (lets say firefox with so many tabs) is eating the cpu why this is not visible on ksysguard?
Is the number of applications running too high? Is the number of virtual desktops causing this problem?? Why the system d seems to be relatively high?
> My processor is a Intel Core 2 Quad CPU (8400 @ 2.66)
I have an “Intel(R) Core™2 Quad CPU Q9550 @ 2.83GHz”. I have nine workspaces (oS 11.4),
8 GiB, large swap (unused now), firefox with several windows and tabs, thunderbird… So very
similar to your setup. My average load is below 5%.
Your systemd running at 12% is weird. Very.

Tonight I will attempt to create a setup like yours and see what I get. Of course I do wonder why some many sessions are required, but lets see what I get tonight.
sessions are needed for handling many tasks. Instead of closing and opening windows one just switches desktops. We can assume for now that these are needed

Sessions or workspaces?

But the name is not “sessions”. Sessions involve entering login and password, not a click.

Oh yeah. Beagle and some related systems are forbidden on my systems. I
would really like to get rid of akonadi as well, it is a flaky
abomination.
Uninstalling akonadi will usually cause other packages that you may (or may not?) need to get uninstalled along with it, but there’s a simple way to just disable akonadi on a per-user basis, to do this under a user’s home directory in .config/akonadi is a file called akonadiserverrc (that’s dot config btw) and it requires one simple edit in this file to stop akonadi loading when a user logs in
Open the akonadiserverrc file in the editor of your choice (e.g kwrite) and find the line that says: StartServer=true
Change it to say: StartServer=false
Akonadi will no longer start at login after doing that
One thing that struck me is some of the repositories you’re using, don’t know whether any of the issues you have are caused by it or not but I believe it’s not generally recommended to use too much of a ‘mixture’ when it comes to repos and some of those you have I know get added when using ‘1-click’ installs. If that’s the case and you didn’t deliberately add them, when using the 1-click installers I think there’s a tick box saying something like ‘Stay registered to these repositories after installation’, unticking that will prevent ‘extra’ respoitories getting added that you only wanted one (or perhaps a few) packages from. Doing this can help avoid future conflicts
Regarding the unusually high cpu usage by systemd have you tried booting with sysvinit at all? It may be worth trying it once (press F5 at the grub menu screen during boot) just as a test to see if systemd is indeed the cause of your other issues
