Very slow transfer spee


I’m traying to tranfer a 70 Gb file from (Aperture library) in my macbook pro to NAS. It seems start fast but by the time the speed reduces speed till gets block.

I have all devices connected with ethernet cable (laptop + router + NAS)



How are you transferring the files, manually or using an application?

Also check if your router has an firewall that is slowing down the connection.
