Lanbench (PC Recommended)

LANBench is a versatile tool with a range of applications:

: By isolating TCP performance, it helps identify if network slowness is due to cabling, switches, or software overhead. Comparison with Other Tools

Tools like or NTttcp are actively maintained and offer advanced features, such as comprehensive UDP testing, detailed latency metrics, and cross-platform support for Linux and macOS. However, for Windows users seeking a quick, visual tool to test basic TCP throughput without using the command line, LANBench remains a functional and highly accessible choice. LANBench

Note: You will never see exactly 100% of the theoretical speed due to standard TCP/IP protocol overhead, which consumes roughly 2% to 5% of the total bandwidth. Common Troubleshooting Use Cases

LANBench is a simple, command-line based TCP network benchmark tool. Unlike complex, multi-feature tools, LANBench focuses on providing a direct, reliable measurement of the throughput between a server and a client on a network, usually utilizing TCP protocols. LANBench is a versatile tool with a range

For IT professionals managing corporate or educational networks, LANBench provides a straightforward method for baseline establishment and ongoing performance monitoring. Administrators can test specific network segments separately, identifying problematic switches, faulty cables, or misconfigured routers that degrade performance. The tool's low resource usage means it can run on production machines without significantly affecting other operations.

: Supports "Send Only," "Receive Only," or simultaneous "Send and Receive" (full-duplex) testing. Note: You will never see exactly 100% of

The primary goal of LANBench is to measure raw TCP throughput while imposing minimal CPU overhead, ensuring that the results reflect the pure performance of your network rather than being skewed by the test tool itself.

Once the test begins, the client floods the network with data directed at the server for a predetermined amount of time. The software then calculates the average throughput based on how much data successfully reached the destination. Step-by-Step Guide: How to Use LANBench
