iperf service

1. About

TL;DR

iperf is a tool for network performance measurement and tuning. It can produce standardized performance measurements for any network. iperf has client and server functionality, and can create data streams to measure the throughput between the two ends in one or both directions. Typical iperf output contains a time-stamped report of the amount of data transferred and the throughput measured.
