iperf best software for speed testing

Iperf is probably the simplest and the best local speed test tool or via the Internet.
I always hear people complain that the network speed:
"Cristi, my net is not working well!"
And I ask:
“Are you sure it's the net? It shouldn't be a problem on your local network or router! ”
And he wonders:
How can I tell if it's from me? SpeedTest to test with?
Not!
When SpeedTest speed test, we can not determine exactly what speed we have in our local network and local network speed testing is very important to establish its stability.
Along with Ping and Tracert video tutorial, Iperf help us diagnose problems and delays in our network.
Although it is an application that runs on CMD, it is extremely simple and easy to use.

  1. Using Iperf3 successfully checked the actual speed between a PC winXPx32 LAN (server) and another PC with Linux Mint x64. Easy to use and very useful. I knew the approximate speed of transfer between two PCs LAN (in practice), but do not know which is the upper limit that can be achieved with the equipment they have. Now I know because your tutorial and the excellent applications. Thank you!
