Disk i/o overloading and cpu monitoring
I am running deb/unstable with kde 3.3.1 gui on my acer
travelmate laptop (intel centrino cpu).
In the last few days, my laptop has become almost unusable
due to overloading input/output to the disk, that seems
to be triggered both by desktop applications (e.g.kpackages,
kaffeine, etc) and terminal applications entered through
the konsole terminal emulation, e.g. apt-get, that freezes
reading the database.
As I have checked out, enough free swap area seems to be
available, so no reason of such i/o is evident.
Furthermore, from the system monitor on the kde panel
displays one gets that almost 100% cpu is busy due to system
activity, while 'top' is detecting a very low cpu
activity - i cannot explain such inconsistent behaviour.
Here are my questions:
- What can be the origin of such high i/o traffic?
- Why do the kde panel and 'top' report such different informations?
- How can i detect the program (system processes behind
the running desktop application) that is actually performing i/o ?
Thank you for your help
