I'm having trouble setting up my Plex media server in a sense there's a bottleneck somewhere but can't figure out where. I have 2 powered USB drives hooked to my 86U and 2 others hooked to a Minix (android box with gbit). When I play files on the Lining running Kodi, all the files play fine even the ones on the shared network. However when I read through Plex, everything buffers when it's a 4k file. I have enabled samba on my 86u and set it to smbv2 but I dunno how it impacts reading speeds
