Today I Learned - use nettop on macOS to see what's eating your network stack

One of my IBM colleagues drew my attention to nettop 


     nettop – Display updated information about the network


     nettop [-ncd] [-m <mode>] [-t <type>] [-s <seconds>] [-p <process-name|pid>] [-n] [-l <samples>] [-L <samples>] [-P]

            [-j|k|J <column-name[,column-name]...>]


     The nettop program displays a list of sockets or routes. The counts for network structures are updated periodically.

I've already started using this to see what Slack, Firefox etc. are doing, in terms of chatting away ....
