NFSv4 Poor Performance

Hi ALL,

We have enabled nfsv4 and advisory locking in VG8.

Below are the steps we have exported a file system.

a)create the interface and route.

b)create a vdm.

c)create a file system and mount the fs on vdm with Mixed policy.

d)export the fs via PDM (server_2) with nfsv4 option.

Now the issue is with performance of this export is very poor. Export is mounted on the host end and it is giving very poor performance.

Note: In the same existing environment nfsv3 share is there and the performance is good for this.

we have tried with nfsv4 delegation option with None and RW.

Please suggest us any other steps to follow to increase the performance for this nfsv4 export.

Thanks,

Praveen
