Client side

#default (20s) average throughput 
$ iperf3 -c 192.168.1.6

$ iperf3 -c 192.168.1.6 -i 4

# To reverse the direction of packets, use -R
$ iperf3 -c 192.168.1.6 -R

# To run both upstream and downstream, use -bidir 
$ iperf3 -c 192.168.1.6 -bidir

# To test UDP through, use -u and -B <target bandwidth>, default target bandwidth is 1Mbit/select
$ iperf3 -c 192.168.1.6 -u -b 1G
