Download speed, expressed in megabits per second (Mbps), indicates the rate at which your computer can receive data from an online server. Conversely, upload speed refers to how quickly your computer can transmit data to a server on the Internet. Ping, often referred to as "latency," assesses the responsiveness of your Internet connection by measuring the duration it takes for a request to be sent and a response to be received, with results provided in milliseconds (ms). This metric is crucial for understanding how quickly your Internet can react to commands. Jitter, which is derived from various ping measurements, evaluates the stability of your Internet connection; it is also measured in milliseconds, and lower jitter values signify a more consistent connection. Speed Test operates through a vast network of over 5,000 servers worldwide, selecting one that is closest to your current position to ensure minimal ping times, typically reflecting a dependable Internet connection with strong performance. This comprehensive approach helps users gauge their Internet quality effectively.

The Network Speed Test evaluates your network's latency, download, and upload speeds. By leveraging servers globally, it assesses the performance of your internet connection in terms of both latency and throughput.

You can swipe right to view a history of your past tests, making it simple to compare results over time. When conducting a test, certain details about your device and network connection are shared with Microsoft, which aids in enhancing their knowledge of network quality and availability. With your permission, we may also gather data regarding your location during the test. Rest assured that the information collected remains anonymous and is not linked to your identity, nor will it be used for purposes such as targeted advertising. Ultimately, this process contributes to improving overall network services for all users.

LAN Speed Test is an intuitive yet robust application designed for assessing the speed of file transfers, hard drives, USB drives, and Local Area Network (LAN) connections, both wired and wireless. To begin, you select a target folder for the test, which can either be located on a local or USB drive to evaluate its speed, or on a network share for testing your network performance. The tool then creates a file in memory and transfers it bidirectionally, eliminating the influence of Windows/Mac file caching while accurately timing the process, after which it performs the necessary calculations for you. For those with more expertise, there’s an option to connect to a LAN Speed Test Server rather than a shared folder, which helps to bypass slower hard drives by conducting tests from one computer's RAM to another's. This straightforward approach makes it user-friendly and effective for anyone wanting to measure network performance. You'll likely find that LAN Speed Test quickly becomes an essential tool in your network toolkit, enabling you to efficiently assess the speed of your Local Network by conducting tests to and from shared folders. Its simplicity and functionality make it a must-have for both casual users and tech enthusiasts alike.
