When upgrading network hardware (e.g., upgrading from Cat5e to Cat6 cabling, or installing a new 10GbE switch), LANBench verifies that the hardware is actually negotiating at the correct speeds. If a 10 Gbps link is only showing 1 Gbps throughput, the issue can be isolated immediately.

Supports up to 20 multiple simultaneous connections to simulate heavy load scenarios.

The tool is most suitable for IT professionals performing site surveys, advanced home users diagnosing performance issues, and anyone needing repeatable, comparable network throughput measurements. Those requiring UDP testing, cross-platform support, or more advanced features should consider iPerf3 or other alternatives. However, for straightforward TCP benchmarking on Windows, LANBench continues to serve as a reliable choice.

What you are expecting to hit (Gigabit, 10GbE, Wi-Fi 6, etc.)? LANBench

Lower throughput than expected typically indicates a bottleneck somewhere in your network. Common culprits include mismatched cable categories (Cat5 vs. Cat5e or Cat6), network adapters negotiating at 100 Mbps instead of 1000 Mbps, or other devices sharing the connection. Check each component individually to identify the limiting factor.

LANBench may be small in size (approximately 1.9 MB), but it packs a punch for network diagnostics:

While LANBench is excellent, it's not the only tool on the block. Here's how it stacks up against its main rivals: When upgrading network hardware (e

It’s designed to "fill the pipe," pushing your hardware to its absolute limit to find where it breaks. Why Should You Use It?

In today's interconnected world, Local Area Networks (LANs) play a vital role in facilitating communication and data exchange between devices. As the demand for high-speed and reliable networks continues to grow, network administrators and engineers require tools to assess and optimize their LAN infrastructure. This is where LANBench comes into play – a powerful network benchmarking tool designed to evaluate the performance of LANs. In this article, we'll delve into the world of LANBench, exploring its features, benefits, and applications. The tool is most suitable for IT professionals

Unlike speed tests that measure internet bandwidth, LANBench focuses exclusively on local network performance. This distinction is crucial because many factors—from cable quality to router configuration—can impact internal network speeds even when your internet connection performs well. Whether you are a network administrator optimizing a corporate infrastructure or a home user diagnosing slow file transfers between PCs, LANBench provides the numerical data needed to identify bottlenecks.

The tool allows multiple concurrent connections to stress-test the network. How to Use LANBench
