Description Artem S. Tashkinov 2005-12-02 10:04:52 UTC
Version:            (using KDE KDE 3.5.0)
Installed from:    Compiled From Sources
Compiler:          GCC 4.0.2 compilation flags used: -O2 -march=pentium2
OS:                Linux

I have a good CPU (AMD Athlon 3000) and kded deamon eats too much CPU time. E.g. right now I've been running my KDE session for only four hours and kded CPU time is already 3 minutes (from top output):

  PID  USER    PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 2534  user    37  19 31140  14m  10m R  2.3  2.9   2:56.65 kded

Here's kded strace output:

This is a fragment of strace output and it is being repeated every half of a second.
Comment 1 Artem S. Tashkinov 2005-12-02 10:09:59 UTC
Also I've noticed that kded runs ifconfig, iwconfig and route every second
Comment 2 Artem S. Tashkinov 2005-12-02 10:15:14 UTC
Actually it's a bug of KNemo applet which works very dumb.
Comment 3 Artem S. Tashkinov 2005-12-02 10:21:40 UTC
Will someone please reassign this bug to KNemo.

I thought I would ask KNemo developers but KNemo is now a part of KDE extragear so this bug is up to the point.

"Kded with Knemo running consumes too much CPU time by working inefficiently and running ifconfig, iwconfig and route every second."
Comment 4 Thiago Macieira 2005-12-02 11:40:38 UTC
Sure thing.
