Slow network transfers between Mac and Synology NAS

So, this post is a little different from my previous ones.  It's not strictly about photography but it is about something I'm willing to bet is core too most photographers and something often taken for granted.  Most of us have a workstation on which we run our digital darkroom, the Lightroom, Photoshop, Capture One etc apps and a lot of us will have a networked storage device on which we store photographs.
