Running IPerf on a point to point connection

Server Side-
    iperf3 -s-i 1

Client Side-
    iperf3.exe -c 172.30.250.25 -w 1025kb -P 10 -i 4


-s Server
-c Client
-w window size, optional, but reducing window size requires less CPU.
-i Sets the console output interval, -i 1 updates every 1 second
-P is the number of processes - each is good for about 50 Mbps. So for 200 Mbps you'd want -P 4
