  • program to calculate the speed of the local network.
Provide the necessary conditions for measuring the speed of your local network. To do this, shut down the applications that in any way involves traffic. This is necessary in order to avoid inaccuracies when measuring. Close programs that use your PC resources to a large extent, as performance is also largely can affect the speed of data transmission and reception. Configure firewalls so that they do not interfere with the passage of the stream of test information through the local network.
Download a special program to measure the speed of local network. You can use your regular applications running in the portable or installed, and the console utility. In the first case, programs are usually part of others, such as AIDA. It includes a special utility which performs speed measurement and displays the results in graphs. You can download it from official developer's website and install on two computers connected by a network, and then perform necessary actions to calculate speed.
If you do not want to install additional software to measure the speed of local network, use the console utilities. For example, iperf, Netspeed, PCATTCP, NetCPS, and so on. They all work on the same principle and have a set of specific commands that you need to know to perform a measurement of the speed of your local network. Usually their work is built on the file transfer size 10-100 megabytes for convenience, then the calculations are done automatically, reducing errors to a minimum. You can also calculate the speed yourself, but there will be inaccuracies.
