Lanbench

A: Yes, when downloaded from reputable sources like the developer's website (zachsaw.com), LANBench is clean and free from viruses or malware.

Click the button to put the application into server mode. Note the local IP address of this machine. 2. Configure the Client Machine Open LANBench on the second computer. Navigate to the network configuration settings.

To run the LANBench server, use the following command: LANBench

The main window will display both and average data transfer rates in Kbps (Kilobits per second). To convert to the more commonly used Mbps (Megabits per second), simply divide the result by 1,024.

LANBench operates using a model.

is a free, portable network benchmark utility designed to test the network throughput and performance between two computers. Unlike complex enterprise network testing tools that require extensive command-line knowledge, LANBench provides a simple, lightweight Graphical User Interface (GUI) to measure TCP network performance.

To evaluate the performance of LANBench, we conducted several experiments on a Gigabit Ethernet network. The server and client were connected to the same switch, and the distance between them was approximately 10 meters. We ran the benchmarking test for 10 minutes, with a packet size of 1400 bytes and a buffer size of 64 KB. A: Yes, when downloaded from reputable sources like

is a minimalist, open-source network benchmarking utility. Unlike popular tools like iPerf3 or Netperf—which rely heavily on the operating system's TCP/IP stack and can be limited by CPU performance at high speeds—LANBench is designed to test the raw maximum achievable throughput of a network link by minimizing software overhead.

| Parameter | Options | | --- | --- | | | Set the length for each measurement run (e.g., 10 seconds, 30 seconds, 1 minute) | | Packet Size | Adjust the size of data packets transmitted during testing (from small control-sized packets up to large jumbo frames) | | Connections | Configure up to 20 simultaneous TCP connections to simulate real-world multitasking or heavy load scenarios | | Transfer Mode | Select between bidirectional communication (send and receive), unidirectional upload testing, or unidirectional download testing | | Server Address | Input the IP address of the listening computer (e.g., 192.168.1.105 ) | | Port Number | Match the port configured on the server side (default port is 8988) | To run the LANBench server, use the following

| Feature | LANBench | iPerf3 | |---------|----------|--------| | | Extremely high; designed to saturate 10G/40G links on modest CPUs | Moderate; can become CPU-bound on 10G+ without tuning | | Protocol | Raw socket or simple UDP/TCP wrapper with minimal overhead | Full TCP/UDP with congestion control, window scaling, etc. | | Test Modes | Unidirectional, bidirectional (full duplex) | Unidirectional, bidirectional, reverse, UDP jitter/loss | | Reporting | Simple: average, min, max throughput | Detailed: intervals, retransmits, CPU utilization, OWD | | Cross-Platform | Windows, Linux (varies by port) | Broad: Linux, Windows, macOS, BSD, Android, iOS | | Latency Measurement | Not built-in (focus on throughput) | Yes, via --interval and UDP timestamps | | Community/Support | Small, niche | Very large, actively maintained |

LANBench is a dedicated network performance testing tool designed specifically for Windows environments. As an open-source TCP-only benchmarking utility, it excels at measuring real-world throughput between two computers on a local area network (LAN) with minimal CPU overhead. Developed by Zach Saw and first released in the late 2000s, this tool has remained relevant due to its simple interface and accurate measurements.
