How to Benchmark Network Speed and Throughput with NetIO-GUI

NetIO-GUI is an open-source, lightweight Windows graphical user interface (frontend) for the classic multi-platform command-line utility netio. It is designed primarily to benchmark network performance, measuring network transfer rates and ICMP response times between two endpoints (peers) using different packet sizes and protocols. Key Features

Peer-to-Peer Benchmarking: Measures throughput and latency between two specific network nodes (e.g., assessing a client-to-server or peer-to-peer VPN tunnel quality).

Multi-Protocol & Variable Data Streams: Supports both TCP and UDP data transfers with variable segment and packet transmission sizes.

Built-in SQLite Database: Automatically logs all metrics and historic test results into a local SQLite database file, enabling seamless tracking and easy comparisons.

Flexible Exports: Allows users to export benchmarking data easily into CSV or Excel sheets for advanced reporting.

Portable Deployment: Available as both a standard setup installer and a portable standalone executable that can run directly off a USB flash drive. Step-by-Step Setup Guide

Because NetIO-GUI functions as a peer-to-peer testing solution, you must deploy it on two different computers across the network architecture you want to test.

Download and Distribute: Download the latest client from the official hosting platform like NetIO-GUI on SourceForge. Put the executable on both test machines. Configure the Server Node: Open NetIO-GUI.exe on the first computer. Click on Server Mode and select Start Server. Note down the local IP address displayed on the screen. Configure the Client Node: Open NetIO-GUI.exe on the second computer. Select Client Mode.

Type the Server’s IP address into the designated address block.

Run the Benchmark: Select your desired protocol (TCP/UDP), choose the packet parameters, and click Start Measure to begin tracking throughput. User Review & Performance Assessment
