Sorry for the noise.
I have find out the cause in our setup and case: We gathered too many

Hello, Loic
the following is my steps and configurations:

same host machine.
(2) Each osd had one 1T HDD.
(3) I set the erasure coding pool profiles:

The results indicates the write throughput can be enhanced

Don't find something strange.
Could you paste your ceph.conf? And restart this osd with
