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:
