As you may be aware of latest versions of NFS/SMB protocol have added 
the support for Delegation/Leases which shall guarantee certain 
semantics to their clients with respect to file sharing. Protocol 
clients thus are guaranteed cache consistency and can do aggressive data 
caching.

There is on-going effort to support such Leases on Gluster.

Apart from that, NFS-Ganesha server currently does attribute caching of 
the files and directories being accessed. I am not sure if there is any 
caching being done by SMB server. Request others to comment.

Thanks,
Soumya
