Hi， Recently, I upgraded Ceph from 15.2.16 to 17.2.6, but I found that OSD CPU usage increased from 30% to 90% or more, and OSD subop_w_latency increased from 600us to 5ms. This is incredible. My hardware environment: 12 nodes x 12 NVMe (Intel P4510 4T) I tried to set the OSD configuration to the default value and saw no improvement either. Have you ever encountered this problem？ What might have gone wrong?
