I've got a new QNAP TS-251+ NAS drive. Fedora detected it with no problem and everything works, I can copy files to and from it using the Gnome "Files" file manager. However, the copies are very, very slow. It looks like the top speed is around 1.2MB/sec. From my wife's Windows box, we're seeing speeds more like 60-70MB/sec.

Is this a known problem with Fedora's Samba support or can anyone recommend a method to speed up access to the NAS or further diagnose the problem?
