For high performance, I tried to enable the PNFS option, then i mount nfs by
mount -t nfs -o vers=4.2,sec=krb5p 192.168.5.84:/ /mnt/nfs

SO, I doute that, version 4.2 of NFS-GANESHA or PNFS of NFS-GANESHA is Completed?

What FSAL are you using? We have limited PNFS support, not all FSALs support it and it has not had recent attention from any of the active contributors. Do note that PNFS is an optional feature, so not having it does not make Ganesha incomplete for 4.2.

@tojoyccnu please check the wiki, it show some notes abt pNFS

pNFS
NFS-Ganesha has support infrastructure for pNFS but efforts in this area have not been active for many years and pNFS is not currently supported by the active community.

@tojoyccnu any feedback?
