Default Value: (null)
Description: Use this option to make NFS be faster on systems by using more memory. This option specifies a multiple that determines the to tal amount of memory used. Default value is 15. Increase to use more memory in order to improve performance for certain use cases.Please co nsult gluster-users list before using this option.

Option: nfs.trusted-sync
Default Value: (null)
Description: All writes and COMMIT requests are treated as async. This implies that no write requests are guaranteed to be on server disks when the write reply is received at the NFS client. Trusted sync includes trusted-write behaviour. Off by default.
Option: nfs.trusted-write
Default Value: (null)
Description: On an UNSTABLE write from client, return STABLE flag to force
client to not send a COMMIT request. In some environments, combi ned with
a replicated GlusterFS setup, this option can improve write performance.
This flag allows user to trust Gluster replication logic to sync data to
the disks and recover when required. COMMIT requests if received will be
handled in a default manner by fsyncing. STABLE wr ites are still handled
in a sync manner. Off by default.
My question is when would you want to use these features. When do you not want to use these features? My environment has a requirement for glusterNFS right now because the FUSE client has shown instability under certain load that I cannot recreate with glusterNFS.
