Synology and macOS Sierra – slow transfer or disconnected shares

Mounting shares on my Synology NAS via AFP was very unstable and sometimes shares were disconnected for no real reason, so I finally decided to move to SMB. AFP is deprecated anyway and even Apple suggests to move to SMB. While I usually had 100MB/s transfer speeds on AFP, I only got around 30MB/s on SMB. So after some research I found the following solution:

  1. Set SMB version to SMB V3 on the Synology (File Services > Windows > Advanced)
  2. Disable „SMB Signing“ on your Mac clients by creating /etc/nsmb.conf:
#> sudo vi /etc/nsmb.conf
[default]
signing_required=no
