[ceph-users] Ceph Cluster slowness in production

Hello team, I have configured a ceph cluster running on ubuntu 20.04 , with 16 HDD for data and 4 SSD for journaling on each host. the total cluster size is 150 TB usable with a replica of 3. The cluster is in production , integrated with openstack with different pools: Volumes, vms, cinder and cinder-backup. The problem I have is this : For linux servers there is no slowness , but on windows servers is worse , they are very very slow, some of those servers have been migrated from vmware to openstack using coriolis , the network interfaces and switches are 10Gbps. Kindly advise the way I can speed up my cluster to avoid the slowness. Best regards Michel
