[NFS-Ganesha-Devel] NFSv4.0 and NFSv4.1 performance

Hello, We observing difference in performance while R/W between NFS4 v4.1 and v4.0 v4.1 is considerable smaller than v4.0(We are trying with authentication as kerberos5) Is this is expected performance degradation from v4.0 to v4.1 ? Thanks and Regards Harsh Vardhan
