7.3.1 Configuring NFS Buffer Size Parameters for Oracle Database

Set the values for the NFS buffer size parameters rsize and wsize to 32768.

For example, to use rsize and wsize buffer settings with the value 32768 for an Oracle Database data files mount point, set mount point parameters to values similar to the following: 
nfs_server:/vol/DATA/oradata /home/oracle/netapp nfs\
rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,actimeo=0,vers=3,timeo=600
Direct NFS Client issues writes at wtmax granularity to the NFS server.
