Recently, poor performance. Network-related?
Wired connection to a ROKU-3 Model ????. CAT6 cable from my main switch direct to ROKU

Performance expectation for ROKU-3 ?
Without going into deep details yet, what should I expect out of my fairly old ROKU 3? Or my Plex setup.
I store all my media on a Plex server running on a dedicated PC (re-purposed HP Compaq Pro 6300 i3 with 4GB RAM). ROKU is connected via CAT6 cable to a gigabit switch (TP-LINK TL-SG1016DE), where all other network devices connect.
As a rough guide, I can copy files from PCs to my NAS (XigmaNAS running on a different dedicated server of similar specs to the Plex server) at 100+ MB/sec, so I think my network “infrastructure” is sound.
But my ROKU 3 (Model 4200X) can’t play anything above 480p; any attempt at 720p or 1080p content fails. Advertising copy foe this device sez “Plays 720p HD & 1080p Full HD Video”.
I need some guidance as to whether I should accept this performance level, or if I should be investigating further. And if this sounds like a Plex problem, a hardware/CPU/disk problem, or a network/cable/switch problem.
Any suggestions welcome.
