Hi Cephers, Hi Gregory,

I consider same case like here, commit_latency==apply_latency in ceph osd
perf

http://lists.ceph.com/pipermail/ceph-users-ceph.com/2018-January/024317.html

What's the meaning of commit_latency and apply_latency in bluestore OSD
setups[? How useful is it when troubleshooting? How does it correspond to
separated block.db and block.wal ?

Thanks
Jakub
