EoL? They’re releasing betas regularly and announced 13.3 for Q2. You mean how they’re sort of winding down with scale taking the bulk of dev cycles? Not much to change with the platform, and security fixes will be backported to CORE. I think SCALE still doesn’t fit my use-case, hut when it does, and jails go away with CORE, I’ll shed a tear and pour one out for my homie.
Kodi on my 2015 Nvidia Shield doesn’t stutter for me playing back 30GB+ 4k files on a 1Gb network from an ancient (2012) AMD Athlon TrueNAS box. It could be network related, but you can test this from another machine (laptop, desktop, etc) or by using local playback on the pi. I have cheap network hardware, and have never needed better. All this is to say Kodi mounting NFS shouldn’t need much bandwidth or high end gear. Perhaps the issue is on the playback side. Good luck!
