I'm a long fan of unraid. Been on it's since 2013ish. Finally upgraded to 6 as I was holding out as I was using Resilio Sync plugin. So no changes other than OS. With 5.6 I was playing high bit rate 4k content zero issues. Tried to play a movie, 720p and it stopped every 3min or so and my Kodi was bitching about source being too slow. I run an IT company. Not new to hardware or Unraid. Checked and it shows 1G on Eth port. Why the crazy slow read speeds? Im going to swap back to 5.6 and try some movies and if it plays fine, it completely proves it's OS issue. Any help greatly appreciate.
Just for full disclosure, I am full RFS, and am going to move to XFS once an extra drive shows up. Not because I care but because I want to be current for support.
