My Suse 11.2 with kde desktop has recently suddenly become incredibly slow. The effect noticed is frequent long waits (>5 seconds at times) before any response from a desktop command.
Looking at System Monitor shows only 10 to 20% usage of cpu. As far as I can tell there is no significant shortage of disk space (unless it’s swap?) and there have been no hardware changes.
Currently the only apps I tend to keep running are Firefox (3 tabs) and Thunderbird, with turboprint monitor in the background.
I am connected via samba to another PC and printer, but there has been no change with that since installation.
I am at a loss to think what could now be causing this apparently sudden change in behaviour - Suse was remarkably quick originally.
Is Nepomuk currently indexing your files right now??? That could be one reason why the sudden slow down. If it is running you could stop the indexing and see if that speeds up your computer.

Not sure what Nepomuk is. But this has been going on for two or three weeks now.
Nepomuk is a desktop search service introduced in KDE 4.x - The icon for this service is located in the taskbar it looks like an swirly icon 4 loops(best way for me to describe…lol If it isn’t there…then it isn’t indexing your computer.

Thanks ! No, it isn’t there, so that’s one suspect out of the way.

Look for disk activity (led blinks too much) or disk errors in the log.

Open a console and run top note what is eating the cpu cycles when the machine slows down.
Also do you see a lot of disk activity or hear a tick sound when this happens? It could be bad disk sectors and a sign of failing hardware.
Running top shows averaged cpu usage around 10 to 15 percent, nothing alarming visible. No sound or sight of excessive hard disk activity either.
Not sure which log file to examine?

did you try without any network connection ?

Look for iowait.

Makes no difference. With the router on, connected to internet and one printer only, there is negligible activity happening.
The main symptom is that, after clicking on say a link, or the dolphin icon, or indeed often any keyboard key, there is this delay sometimes up to several seconds but often one or two seconds, before there’s any response. It happens sometimes when typing - the line stops for a time, and then the rest of the typed line appears. Then at other times the response is the usual instantaneous one. Even, for example, in Dolphin when I click on an icon or a menu this delay occurs very often, but not always. The same goes for the scroll bar response. All this is with only firefox running (so I can type this !!).
Let’s have a look at the repositories you have installed on your system please. In a terminal please enter the following and paste in quote tags back here :
zypper repos

PS:-
I have now deleted the first three of the abve which related to the old Suse 10.3.
It has not made any difference to the problem.
I have looked under Hardware Info in Yast, under cpu, and found a line:-
Bogus Millions of Instructions per Second 1800.04.
Is this significant, or does it just refer to the idle cycling ?

Still you haven’t looked at the logs.

i assume, you are NOT using nvidia drivers?
please post your kernel version:
$ uname -r
also give the deadline scheduler a try:
either via yast2 (HIGHLY RECOMMENDED):
# /sbin/yast2 system_settings
or manually for each disk:
# echo "deadline" > /sys/block/<DEVICE_NAME>/queue/scheduler
to change back use
# echo "noop deadline [cfq]" > /sys/block/<DEVICE_NAME>/queue/scheduler
Simply removing the 10.3 repos will not do anything we do not know what may have been installed from them.
I need you to tell me which logs and how to access them please
