noatime implies nodiratime as far as I know.

And yes, it can help for databases for example. I think official =

recommendation for MySQL and PostgreSQL is to use noatime. There is a post =

by Theodore T=B4so somewhere about make clean workload on Ext4 with noatime=
, =

relatime and strictatime handling and only noatime considerably reduced the =

amount of writes.

noatime is a generic tuning option which can help with other filesystems as =

well.
