Modifying the NFSv3 and NFSv4 TCP maximum transfer size
You can modify the -tcp-max-xfer-size option to configure maximum transfer sizes for all TCP connections using the NFSv3 and NFSv4.x protocols.
About this task
You can modify these options individually for each storage virtual machine (SVM).Beginning in ONTAP 9.4, the v3-tcp-max-read-size and v3-tcp-max-write-size options are obsolete. You must use the -tcp-max-xfer-size option instead.
Example
The following command sets the NFSv3 and NFSv4.x TCP maximum transfer size to 1048576 bytes on the SVM named vs1:
vs1::> vserver nfs modify -vserver vs1 -tcp-max-xfer-size 1048576
