 No. You host the server on the same computer you cannect to - that only tests Linux's local network which is fast :-)

Hmm yeah. The Mac should be running the iperf server, and I assumed the server was 10.0.1.55. The LE client should be running iperf -c ip-address-of-Mac -t 60 -i10.  

 Brew installed an old version of iperf on my Mac so i need to install iperf3 to be compatible with libre.
