Lanbench Jun 2026
Ideal for users who need a direct, no-frills benchmarking tool.
Preferred for users who need to save test results in a database for later comparison.
He didn't need the bloated, commercial network suites that took an hour to configure. He reached for his digital swiss-army knife:
Setting up LANBench takes less than five minutes. Follow these steps to benchmark your local throughput: Step 1: Prepare Your Hardware Connect two computers to the same local router or switch. LANBench
At its core, LANBench measures network throughput by establishing TCP connections between a server and client. The software implements a basic client-server architecture: one computer runs as a server listening for incoming connections, while the other sends test data as a client. This approach eliminates variables like disk I/O speeds that can skew results in file-based tests, providing a cleaner measurement of network capability.
Using LANBench is straightforward. Here’s a step-by-step guide to get you started:
Follow these steps to set up and run your first network benchmark test using LANBench. Step 1: Prerequisites Two computers connected to the same local network (LAN). The LANBench executable downloaded onto both machines. Ideal for users who need a direct, no-frills
If either the client or server machine is older, a high-throughput network test can max out a single CPU core. Check your Task Manager during a test to ensure your processor isn't bottlenecking the data flow.
: Users can adjust the size of the data blocks used for each send and receive request. This helps determine how a network handles small packets (like VoIP/gaming data) versus large packets (like massive file transfers).
Allows you to change the size of the data packets being sent, helping to identify how your network handles small packets (like gaming traffic) versus large packets (like file transfers). He reached for his digital swiss-army knife: Setting
If you are ready to test your network, let me know your environment setup! Tell me if you are testing connections, what network speeds you expect to hit, and whether you are running into any specific slowdowns you want to troubleshoot. Share public link
Keep the default port (unless your firewall requires a specific port change). Step 4: Run the Benchmark On the client machine, click .
The local IP address of the computer you designate as the server. Step 2: Set Up the Server Open LANBench on the first computer. Click on the button.
It is specifically built to use as few system resources as possible, ensuring your processor doesn't become a bottleneck during the test. Winsock 2.2 Foundation:
