NFS Config vs Ceph / GlusterFS

[dovecot at ptld.com]

Do all of the configuration considerations pertaining to using NFS on

    https://doc.dovecot.org/configuration_manual/nfs/

equally apply to using something like Ceph / GlusterFS?


And if people wouldn't mind chiming in with which (NFS, Ceph & GlusterFS) they feel is better for maildir mail storage on dedicated non-container servers?
Which is better for robustness / stability?
Which is better for speed / performance?


Thank you.
