Hi Paul,

thank for your answer. Can you explain clearly for me about:

- How does ceph's deleting object operator work? (it mean about how delete object flow in ceph works?)

- using s3cmd tool which install in client to delete object, how to improve speed of delete object operator (objects/s) with it, current speed is 32-36 objs/s at point 90M-100M object, using 1 client, running 1 process delete ( s3cmd del -r s3://mybucket/2019)

thank you very much

--max-concurrent-ios helps with deletion speed, there's also a memory
leak during deletion which is being fixed here:

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:
