Are you troubleshooting a , or just verifying a new setup?

The software is completely portable. It runs directly from an executable file without modifying system registries. Step-by-Step Guide: How to Use LANBench

To get the most out of LANBench, follow these best practices:

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 LANBench

While LANBench is excellent for quick, straightforward TCP throughput testing, other tools offer broader capabilities:

Close file transfers or internet-heavy applications on both machines.

LANBench is a free, portable network performance benchmark tool built on the TCP/IP network protocol. Unlike standard file-copy tests—which are often bottlenecked by slow hard drives or solid-state drives—LANBench tests network performance by transmitting data directly from the system memory (RAM) of one computer to the system memory of another. Are you troubleshooting a , or just verifying a new setup

After running your tests, you might find your speeds are lower than expected. Here is what to check:

It requires no installation. You can run it directly from a USB flash drive.

A built-in feature of the broader AIDA hardware auditing suite, offering visual graphing tools. Step-by-Step Guide: How to Use LANBench To get

, allowing users to simulate heavy traffic environments to see how hardware handles congestion. Customizable Testing : Users can configure specific parameters, including: Packet Size

One computer acts as the server, and another as the client. The server listens on a specified port, while the client initiates the connection and starts the test.
