NFS freezes/stalls after each file

General system Newbie

I have setup an NFS share on a WD MyCloud device (its an old gen1 device). I have mounted it using the following /etc/fstab entry

192.168.1.101:/shares/Home/ /media/nfs2 nfs nfsvers=3,defaults,rw,noatime,nodiratime,rsize=1048576,wsize=1048576 0 0

When I am copying files over, it transfers the file at about 12Mbps and then freezes for 20 or 30 seconds, before moving on to the next file.

Wondering if anyone has any suggestions? I mainly use the share for large files, home movies and stuff like that, and since its an older device, it only supports nfs3.

How do I work out what version I am using?

I use a script that has the line:

sudo mount -t cifs -o rw,user=guest,password=,vers=3.0,file_mode=0777,dir_mode=0777 //192.168.4.35/steve /media/steve/

Never tried fstab. It was inherited from a friend who passed away, so I have no manuals etc.
