Suspicious activity and slowness ...

[Peter Nabbefeld <peter.nabbefeld@xxxxxx>]

Hello,

since some days, I'm noticing HD is too busy, and my laptop is very slow 
in some cases.

Are there any invisible background threads running? How can I find out 
about those? Running top, cpu use should be only about 30%, so it should 
wait for tasks to be executed, instead.

Kind regards

Peter
