I did the obnoxious task of updating ceph.conf and restarting all my

I have some spare memory on my target host/osd and increased the target
memory of that OSD to 10 Gb and restarted. No effect observed. In
fact
mem usage on the host is stable so I don't think the change took effect
even with updating ceph.conf, restart and a direct asok config set.
target
memory value is confirmed to be set via asok config get
Nothing has helped. I still cannot break the 21 MiB/s barrier.
Does anyone have any more ideas?
For recovery you can adjust the following.
osd_max_backfills default is 1, in my system I get the best performance
with 3 and wpq.
The following I have not adjusted myself, but you can try.
osd_recovery_max_active is default to 3.
osd_recovery_op_priority is default to 3, a lower number increases the
priority for recovery.
All of them can be runtime adjusted.
