           Summary: KDE/Plasma Performance constantly decreases until
                    System freeze. Unusable.
           Product: kde
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: oliver.maurhart at gmx.net


Version:            (using KDE 4.2.1)
Compiler:          gcc 4.3.3 Gentoo ... all stuff compiled from source.
OS:                Linux
Installed from:    Gentoo Packages

Since KDE 4.2.0 the overall system performance and experience degrades. X11 and
Plasma are constantly running on 20%-30% CPU; quite often even more.

Especially when I startup kmail/kontact, which works with a local spamassassin,
the system becomes quite unusable. Konsole is starting somehow fine but gets
constantly worse and sluggish.

... and sooner or later the whole desktop freezes. Sometimes I get along
waiting for about 10 sec; sometimes I'm that frustrated to pull the plug. I
consider this as a crash.

I hoped that KDE 4.2.1 would address some of these issues, but it didn't.

Some data:
- Linux demandread 2.6.28-gentoo-r3 #1 SMP PREEMPT Tue Mar 10 09:48:39 CET 2009
i686 Intel(R) Pentium(R) M processor 2.13GHz GenuineIntel GNU/Linux
- X.Org X Server 1.5.3
- xf86-video-ati 6.11.0

Enabling/Disabling desktop effects doesn't make any difference.

How can I help? Is there anything I can do?

As such KDE 4.2.x is now not really usable for me.
