Lanbench ^new^ -

Users can adjust packet sizes to simulate different types of network traffic.

It achieves this by using a simple, custom protocol over raw sockets (or high-performance transports) and focusing on pure data pushing/pulling without complex application-layer logic. The primary goal is to answer the question: "What is the absolute maximum bandwidth this network cable, switch, and NIC combination can provide, ignoring OS protocol stack bottlenecks?"

It is specifically built to use as few system resources as possible, ensuring your processor doesn't become a bottleneck during the test. Winsock 2.2 Foundation:

If you are planning to test your network setup, let me know: LANBench

LANBench fills a specific but important niche: . While it lacks the polish and feature richness of iPerf3, its simplicity is its strength. For network engineers debugging high-speed LAN performance issues, or for validating that a 10G link truly can achieve 10G, LANBench is an indispensable tool. However, for comprehensive network characterization including TCP behavior, latency, and multi-stream fairness, iPerf3 or Netperf remain superior choices.

Whether you're a seasoned network administrator troubleshooting a stubborn bottleneck or a DIY enthusiast eager to know if your new Gigabit switch is performing as promised, you need a way to measure your local network's true potential. Enter : a lightweight, free, and remarkably straightforward tool designed to put your Local Area Network (LAN) through its paces.

Offers versatile testing profiles including Send Only, Receive Only, and simultaneous Send and Receive. Technical Specifications & Architecture

The industry standard for network testing. It is a powerful, command-line-driven utility available on Windows, macOS, Linux, Android, and iOS.

Users can modify the size of data packets sent across the network to see how hardware handles small packets versus large payloads. Winsock 2

Note: You will never see exactly 100% of the theoretical maximum speed due to network overhead (headers, routing data, and acknowledgments required by the TCP/IP protocol). Troubleshooting Common LANBench Issues

The second computer acts as the sender. It connects to the server’s IP address and floods the connection with data based on your configuration.
