Hi Wenruo, thanks for your answer. Unfortunately it seems you overlooked what
was described as problem in the initial description:

https://bugzilla.opensuse.org/show_bug.cgi?id=1063638#c0
states that the priority as configured in /etc/sysconfig/btrfsmaintenance is
not regarded in the triggered maintenance jobs. I could easily check this on my
up-to-date openSUSE Leap 15.1 system by calling
sudo sh -x /usr/share/btrfsmaintenance/btrfs-balance.sh
and observing that the maintenance jobs are started without any nice level and
the system responsiveness is impacted. Seeing that the bash script has not been
changed to regard e.g. "idle" priority this is understandable. It feels that
the changes you have applied actually help to prevent a critical performance
degradation so an improvement *is* noticeable but the original problem is still
present, at least partially hence reopening.
