iPerf3 is a command line tool to measure the achievable bandwidth on IP networks. It makes it easy to get an accurate count of bandwidth you can expect to see between two hosts on the internet.
brew install iperf3
sudo yum install iperf3 sudo dnf install iperf3
sudo apt install iperf3
iperf3 -c 10.0.0.1
By default iPerf3 uses port 5001, if you would like to specify a different port you can use the -p switch
iperf3 -s -p 9001 iperf3 -c 10.0.0.1 -p 9001
