Lanbench < 2027 >

The implementation leverages Windows I/O completion ports and multithreaded architecture, enabling efficient handling of up to twenty simultaneous connections without overwhelming the host system. This technical foundation, based on Winsock 2.2, allows LANBench to accurately simulate real-world network behavior in controlled environments.

: Supports "Send Only," "Receive Only," or simultaneous "Send and Receive" (full-duplex) testing.

: Supports both "Send" and "Receive" modes to test upload and download speeds independently. Low Resource Usage

: By isolating TCP performance, it helps identify if network slowness is due to cabling, switches, or software overhead. Comparison with Other Tools LANBench

LANBench may be small in size (approximately 1.9 MB), but it packs a punch for network diagnostics:

: Specific time periods for benchmarks (e.g., 10 seconds).

While there are many complex command-line utilities available for network testing, sometimes you need a tool that is lightweight, portable, and straightforward. This is where shines. : Supports both "Send" and "Receive" modes to

Expect speeds around 2200 Mbps to 2300 Mbps .

LANBench is designed to measure the performance of LANs by sending and receiving data packets between two endpoints. The tool consists of two main components: a server and a client. The server component listens for incoming connections and sends data packets to the client, while the client component connects to the server and receives data packets.

: Does not require installation and leaves no traces in the Windows registry; it can be run directly from a USB drive. is a lightweight

Network performance testing is critical for maintaining healthy IT infrastructure. Whether you are a network administrator managing an enterprise data center or a tech enthusiast optimizing a home gaming setup, you need reliable tools to measure your local area network (network throughput).

is a lightweight, Windows-based tool designed to measure the TCP throughput between two computers on the same network. It is designed to be as simple as possible, often favored by network administrators and enthusiasts because it doesn't require complex installation, command-line proficiency, or expensive enterprise licensing.

If your LANBench test fails or displays unusually low speeds, use this troubleshooting checklist:
