Hi All, I have a repeatable condition when the object count in a pool gets to 320-330 million the object write time dramatically and almost instantly increases as much as 10X, exhibited by fs_apply_latency going from 10ms to 100s of ms.
Can someone point me in a direction / have an explanation ? I can add a new pool and it performs normally. Config is generally 3 Nodes 24 physical core each, 768GB Ram each, 16 OSD / node , all SSD with NVME for journals. Centos 7.2, XFS Jewell is the release; inserting objects with librados via some Python test code. Best Regards Wade
