Hi everyone,
In a scenario where running benchmarks on dedicated hardware is not
possible, I'm trying to momentarily cap the I/O bandwidth used by
interactive user sessions while benchmarks are running, in order to improve
the stability of said benchmark's I/O performance.
Is this on cgroupsv1 or cgroupsv2?
IIRC there was some issue that the block io controller wasn't fully
recursive on cgroupsv1. It should work on cgroupsv2.
This is on a hybrid cgroup configuration. I (perhaps mistakenly) assumed
that modern systemd (v246) will use the cgroups v2 hierarchy in that
case, even though cgroups v1 is still exposed for compatibility with
older apps.
