Are you sure about the update on every start? Does the update happen only if
the benchmark result is < 500 iops?
Looks like the OSD does not remove any set configuration when the benchmark
result is > 500 iops. Otherwise, the extremely low value that Michel reported
earlier (less than 1 iops) would have been updated over time.
I guess.

The OSD run bench and update osd_mclock_max_capacity_iops_{hdd,ssd} every time
the OSD is started.
If you check the OSD log you'll see it does the bench.
