I have continued testing this and I have discovered more things, here they are:
-When I try to play a film and it bugs it starts using 300mbps of the RX connection, I imagine that form the NFS share server, once it starts playing it lowers to 98mbps, no idea why:
-Also I do not know why the RX is higher than the TX, as should be the same, the same data downloaded from the NFS share via RX and uploaded to the browser or other device via TX:
-And finally, here you can see the download connection when playing from internet explorer, there was not needed to download at 300mbps, it just started playing and downloading at 60mbps more or less:
@Luke are you able to guess anything of this? Because after all the testing I have done, I concluded that something wrong might be happening with emby at this stage.
