Python Script: Network Performance Tester
Writter: Dr Mojtaba Mansour Abadi
Date: 5 December 2018
This Python script is compatible with Python 3.7.
the module provides required GUI to analyze network
performance using 'iperf version 2' for 'Linux' and
'iperf version 3' for 'Windows'.
The bandwidth gauge widget is from:
