LANBench for Windows

LANBench is a free, specialized utility designed to measure the true network performance between two computers on a Local Area Network (LAN). It provides a simple, direct way to benchmark TCP and UDP data transfer speeds, offering valuable insight into the real-world bandwidth capabilities of your connection.

Bidirectional testing

The core functionality of LANBench revolves around its dual-mode operation: running as both a server and a client. The user must install the executable on two separate machines, designating one as the server to passively listen for incoming traffic and the other as the client to initiate the benchmark. 

The program is offered as a single, standalone executable that requires no installation or system-level configuration changes. Although the application does not offer advanced visualization or logging features, its ability to test both TCP and UDP traffic provides a comprehensive view of how different protocols perform over the link.

A focused and portable solution

LANBench is an efficient tool for its singular purpose: benchmarking the speed of a local network connection. Its non-intrusive nature, combined with the versatility of testing both TCP and UDP data, makes it a valuable asset for quick network diagnostics, despite its lack of modern visualization and logging features.
