. It is built on Winsock 2.2 and is specifically engineered for low CPU overhead to ensure that results reflect pure network throughput. Key Features Performance Monitoring:

is a lightweight, portable network benchmarking utility designed specifically for Local Area Networks (LANs). It is used to measure the throughput (speed) and stability of network connections between two computers. Unlike internet speed tests that measure connectivity to an outside server, LANBench focuses purely on the performance of the internal network infrastructure—switches, routers, cables, and Network Interface Cards (NICs).

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.

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
