A: Because LANBench is designed for minimal CPU usage, results are quite reliable for pure network performance, though they may not be 100% exact due to inherent network variability.
Several other tools can measure local network speed, each with different trade-offs. The table below compares LANBench to the main alternatives.
No installation required. It operates as a single standalone .exe file that leaves no traces or registry changes behind.
Observe the real-time display showing current throughput, average transfer rates, and CPU utilization. Advanced Configurations for Accurate Testing LANBench
lanbench -c 192.168.1.100 -p 5001 -t 30 -b 1500 -d both
It functions as both a test server (listen mode) and a test client (sender mode).
: Set the second computer to "Client" and enter the IP address of the server computer. A: Because LANBench is designed for minimal CPU
LANBench is an invaluable, free utility for anyone looking to ensure their network infrastructure is performing at its peak. By measuring internal TCP performance, it bridges the gap between what your hardware is rated for and what it actually delivers.
What you are expecting to hit (Gigabit, 10GbE, Wi-Fi 6, etc.)?
To generate a performance report, you must run the tool on two different computers connected to the same network. Server Setup: LANBench.exe button to prepare the machine to receive data. Note the server's IP address (can be found by running in the Command Prompt). Client Configuration: LANBench.exe on the second computer. File > Configure IP address of the server computer. Adjust settings such as packet size and duration as needed. Running the Test: No installation required
To use LANBench, you must execute the program on two separate machines connected to the same network. One machine functions as the and the other acts as the Client (initiator) .
Highly optimized to prevent system processor limitations from throttling network speed tests, making it reliable for gigabit and multi-gigabit connections.
Measures TCP throughput, which is crucial for file transfers, streaming, and gaming.
