Hi,
Kindly look at the attached screenshot.
How can i find out what is being polled so heavily? I tried looking at
the D flag in ps aux output, but it does not point to anything
special.
well you're doing a ton of disk IO...... during disk IO you're going to get
reduced C states for performance reasons.
How do I find out which process is doing the tonne of disk IO?
I know there are tools like iostat and sar, but i am on MeeGo and its
not there in the repositories. I guess I will have to build them then?
hmmm..... powertop in meego does report things.. but in your case it
just reports the btrfs background workers,
not the guys who cause those to be busy.
(the "D" ones in the screenshot)
can you run "powertop -d" to see if other "D"'s show up?
