TamoSoft Throughput Test is a utility for testing the performance of a wireless or wired network. This utility continuously sends TCP and UDP data streams across your network and computes important metrics, such as upstream and downstream throughput values, packet loss, and round-trip time, and displays the results in both numeric and chart formats. TamoSoft Throughput Test supports both IPv4 and IPv6 connections and allows the user to evaluate network performance depending on the Quality of Service (QoS) settings.

To perform a throughput test, the application uses two components: a server and a client. The server part of the application listens for connections from the client, and the client connects to the server. Once the connection has been established, the client and server send data in both directions, and the client part of the application computes and displays the network metrics.
