Comment 11 for bug 333944

Allright, sorry for flooding:
- the kded4 pushing cpu to 100% only happened once, after the upgrade 8.10-->9.04. So low might be the right priority.

The problem of "lag" in KDE was linked to Xorg and the ati drivers:
Following links helped me find out:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/361060
https://bugs.launchpad.net/ubuntu/jaunty/+source/xserver-xorg-video-ati/+bug/334101

I added in Section "Device" of /etc/X11/xorg.conf
        Driver "ati"
        Option "AccelMethod" "XAA"

Now, K menu, scrolling in web broswer, and so on, everything is displayed at a decent speed.
