RPi 3B+ Buffer / Stuttering Issues

Struggling with buffering / stuttering on an RPi 3B+ with 1GB network and NFS content. Happens at the start of the video and again at random times throughout.

Any thoughts appreciated.

Maybe something changed in the network, we suggest to check your network with iperf3. Please read this howto

iperf output seems fine?
