Hi, I am running a small Ceph Nautilus cluster on Ubuntu 18.04. I am testing cluster to expose cephfs volume in samba v4 share for user to access from windows. When i do test with DD Write (600 MB/s) and md5sum file Read speed is (700 - 800 MB/s) from ceph kernel mount. Same volume i have exposed in samba using "vfs_ceph" and mounted it thru cifs in another ubuntu18.04 as client. Now, when i perform DD write i get speed of 600 MB/s and md5sum of file Read speed is only 65 MB/s. What could be the problem? Any one faced similar issue?
