So I built a renegade SCB with a usb 3.0 drive to replace my aging mycloud as a general network file and music server (movies are done on a dedicated plex). No fancy plugins aside from remote mount so I can use rsync to copy the old NAS folders over.
The whole rsycn job took forever with speeds ~10Mbytes a second despite both devices wired to the same router. Even now when everything is all setup, data saved to it using samba shares is going at an abysmal 5Mbytes a second. Download speeds are zippy and are ~50Mbytes over wifi. What could be causing such a lop sided bottleneck?
