been trying to get some more performance out of my Plex server on RPI 3B. It works fine on files up to about 6-7gb, so quite a lot of movies. But above that, it sits and buffers. From what I found through research, I thought the issue was a bottleneck at the network - with the transfer speed maxing at 10mbps. I got a USB To Ethernet adapter and it seems to be working straight out of the box (TRENDNET one), but I am seeing no performance improvements, and movies are now taking longer to load.
I found some blog posts that seem to suggest that I need to edit /etc/network/interfaces to change it to eth1 - but my file has nothing to change in it.
Any help would be appreciated. I have exhausted my googling skills on this. I am trying to setup iperf to do some tests now, but hoping someone has some advice on this.
