Description Michael Schuerig 2010-09-16 21:06:06 UTC 
Version:           unspecified (using KDE 4.4.5) 
OS:                Linux

KDE runs several background tasks that are not related to actions a user might trigger and for whose completion they wait. Still, these tasks can take up considerable resources and thereby even delay other tasks.

Notable offenders are http_cache_cleaner and virtuoso. Particularly after login these task can drive the load so high that the system becomes effectively unusable for a couple of minutes.

I consider this not just a desirable enhancement, but a downright performance bug.

The cure? Setting the IO scheduling priority of these tasks to idle results in a considerable improvement.

Reproducible: Didn't try
