I install the DAOS and use the mdtest to do some test with -a DFS (one server and one client with 20 cores, the server use 256G DCPM without nvme ssd). But I find the file removal performance is very low and the result shown as follow and I want to know if it is right? Or how to do the performance turning?

The config file of server is :
access_points: ['server-1']
port: 10001
transport_config:
allow_insecure: false
client_cert_dir: /etc/daos/certs/clients
ca_cert: /etc/daos/certs/daosCA.crt
cert: /etc/daos/certs/server.crt
key: /etc/daos/certs/server.key
