Comment # 7 on bug 1111523 from Felix Niederwanger

Hi,

I'm noticing the same in like 1/4 times I update my Tumbleweed laptop. At some
point, the system becomes highly unresponsive, dialogs freeze and you cannot do
any meaningful work for like 1-2 minutes. Even typing bugzilla.opensuse.org
within Firefox was not possible now. In all the cases when I observed this
system unresponsiveness, there was a btrfs maintenance job running in the
background, either a qgroup scan or a scrub.

Is there be a way to lower the priority of those maintenance job runs, so they
appear to be less resource aggressive? I could see that this would be
beneficial on pre-emptive desktop systems like laptops/desktops/workstations.
I think I'm not the only one who would prefer a more responsive system while
background maintenance jobs are running over "let's freeze the system for a
short amount of time and be done with it".
Saying explicitly on desktop systems, on servers the situation is different.
