Dear Ceph team, I builde a object storage using ceph, a cluster with 5 nodes (9 sas10k 2TB (for data)+ 1 nvme (for metadata) in one node , using ceph version 14.2.3, nautilus (stable). My cluster storage over 100M (minlion) objects (files) with file's size ~ 50KB, and I want to delete them to free capacity and improve performance. When I delete object, speed delete object very slow, about ~ 35-36 objs/s at 100M (minlion) objects point, i using command: s3cmd del -r s3://mybucket/2019 to delete. Can you help me: - How does ceph's deleting object operator work? (it mean about how delete object flow in ceph works?) - how to improve speed of delete object operator ( objects/s) - how to delete mult - bestpractice for this usecase - other recommend.... Thank you very much. ----------------------------- Br, Dương Tuấn Dũng 0986153686
