Thanks for the reply anton. 


CPU core count - 40
RAM - 250GB 

We have single active MDS, Ceph version luminous 12.2.4 
default PG number is 64 and we are not changing PG count while creating pool
we have totally 8 server each with 60OSD of 6TB size.
8 server splitted into 2 per region . Crush map is designed to use 2 servers for each pool

You need to give us more details about your OSD setup and hardware specification of nodes (CPU core count, RAM amount)

Hi folks,

We have production cluster with 8 nodes and each node has 60 disks of size 6TB each. We are using cephfs and FUSE client with global mount point. We are doing rsync from our old server to this cluster rsync is slow compared to normal server 

when we do 'ls' inside some folder, which has many more number of files like 1lakhs and 2lakhs, the response is too slow. 

Any suggestions please

Regards
Surya
