When I copy the same file 3 times onto the same share I get an

What's the server? Also try grep MOUNTPOINT /proc/mounts
(where MOUNTPOINT is /whatever your NFS share is)
you should see either nfs2, nfs3, or nfs4 in the second field, then
rsize= and wsize= and further down proto=tcp or proto=udp. It would be
helpful to know what those are on your system.

The server is a self-built machine with an ASRock J4205-ITX mainboard,
8GB RAM, a Samsung 470 SSD as system disk and 2x WD Reds as data disks.
It's running the Debian backport kernel 4.13 (4.14 since yesterday).
The result of 'mount | grep /mnt/temp' on the client is
rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.192.20,local_lock=none,addr=192.168.192.10
where I just set 'soft,proto=tcp', the others were set as default.
