How does iperf measure throughput?

iPerf is an open source, free, network performance measurement tool. It works by simply sending traffic from one host to another and measuring the bandwidth that can be achieved. In addition to the throughput measurement it can give metrics such as packet loss, jitter, and traffic distribution.

What is option in iperf?
