    Hi all,

    I have a really strange issue - when using Finder transfer files TO/FROM my NAS, I'm getting a maximum of <5MB/s.

    If I use CP from Terminal to copy, I get full speeds?!

    Anyone know why Finder is so slow copying data to/from my NAS? I also tried it with my Synology NAS and it is exhibiting the same issue.

    I'm using SMB, but same thing happens with AFP.

    I know the latest macOS update was addressing an issue similar to this.. are you running the latest version?
