    I usually put network tuning configuration directives in /etc/sysctl.conf , have found that SMB suffered pretty badly on default configurations and with the tuning, I can get around 200% performance out of it. However, since OSX Sierra, it appeared that directives in sysctl.conf are no longer being picked up. Anyone know of a way to get around this? Or if I'm missing some permission or setting somewhere to get it working?

    What settings are you trying to change? Have you tested using sysctl?

    I can change it with sysctl -w, but it's not persistent on restart like OSX used to load the sysctl config file.

    sudo visudo put the sysctl command in there for passwordless access to the command, make script to set it how you want add that script to your login items and it will be set every time you login into the machine.
