-        mp_umask                        Mask permissions for mount point

-        use_cache=/var/cache/s3fs       Enabled (to be used with care, because the cache can grow out of control. Also, I haven't noticed much difference using it)

 ### Configure .ENV
 To avoid latency when clicking Diagnostics, my suggestion is to disable BasicPermissionCheck. Otherwise, depending on the number of photos in your gallery, this task can take hours.
