Download speed measured in megabits per second (Mbps), how fast your computer can receive data from a server on the Internet. Upload speed, how fast your computer can send data to a server on the Internet. Ping, also known as “latency”, measures the reaction time of your Internet connection by calculating the time it takes between sending out a request to getting a response. Measured in milliseconds (ms), ping indicates how responsive your Internet connection is. Jitter, based on multiple measures of pings, jitter measures the consistency of your Internet connection. Also measured in milliseconds, the smaller the jitter, the more stable an Internet connection. Speed Test works with a global network of over 5,000 testing servers. The app selects a server nearby your current location with a fast ping, which usually indicates a reliable Internet connection with good throughput.

Network Speed Test measures your network delay, download speed and upload speed. Using servers all over the world, Network Speed Test measures your network connection’s latency and throughput. Based on your connection’s speed, Network Speed Test will tell you what activities you might be able to do, such as stream music or video calls. Slide to the right to see a history of your previous tests for easy comparisons. When you test your network using the Network Speed Test, certain characteristics of your device and the network connection will be sent to Microsoft to help improve our understanding of network quality and availability. If you consent, we may also collect information about your location at the time of the test. The data we collect is not associated with you, and will not be used to identify or contact you or for other purposes like targeted marketing.

LAN Speed Test was designed from the ground up to be a simple but powerful tool for measuring file transfer, hard drive, USB drive, and Local Area Network (LAN) speeds (wired & wireless). First, you pick a folder to test to. This folder can be on a local drive or USB drive, etc. to test the drive speed, or a shared folder on your network to test your network speed. Next, LAN Speed Test builds a file in memory, then transfers it both ways (without effects of Windows/Mac file caching) while keeping track of the time, and then does the calculations for you. For more advanced users, you can test to LAN Speed Test Server instead of a shared folder to take the slower hard drives out of the process as you are testing from one computer's RAM to another computer's RAM. Simple concept and easy to use. You'll find that LAN Speed Test will quickly become one of your favorite network tools! Test the speed of your Local Network by testing to/from network shared folders.

Designed to replicate your real-world connection speed! We are using the latest technology available to test your Bandwidth. This application is designed for testing any connection, from 1 Kbps to 1 Gbps+. Our algorithm automatically detects your stable download and upload speed from our servers. We use HTML5! And no flash or Java is used, so you also get a better understanding of your web browser too. The connection speed in between you and the connected server. Final result will be the average value of the fastest download/Upload burst rates during the Bandwidth. Your test results may vary at different times of the day due to network congestion, and the web browser you choose etc. To get a good understanding of your bandwidth run the test at different times of the day. An application for launching a quick speed test server, without using any commands! This application can run offline! So you can use it to test your Local Area Network/WiFi or put it on a server to test your speed.

Speed ​​Check Light is a lightweight Internet testing tool. This application helps you to measure the downlink speed (download), uplink speed (upload) and delays in the transmission of packets (latency/ping/jitter). The program is equipped with a simple user interface and a multitude of configuration options. One of the major advantages of the Speed Check Light tool is automatic adjustment of the testing algorithms to the type of your connection (WiFi or 2G/3G/4G LTE/5G mobile networks). This ensures high accuracy of the results. Ability to select the default server, built-in map of the mobile network coverage, history of results with detailed information about the tests, IP/ISP address display, ability to filter and sort your results according to various criteria. Two standard units (Mbps and kbps), System clipboard and social networks handling (easy to publish the results on Facebook or Twitter), low demand on system resources.

Test your ADSL, xDSL, cable, optical fiber or satellite broadband connection bandwidth. This speed test relies on an exclusive algorithm allowing you to measure accurately download bitrate, upload bitrate and latency of your connection. nPerf uses a worldwide dedicated servers network, which is optimized to deliver enough bitrate to saturate your connection so that we can measure its bitrate accurately. nPerf speed test is compatible with all broadband and mobile connections: ADSL, VDSL, cable, optical fiber FTTH / FTTB, satellite, WiFi, WiMax, cellular 2G / 3G / 4G (LTE), 5G. The nPerf speed test has been designed by telecom enthusiasts to enable you to accurately measure the speed of your Internet connection easily, in only one click! Oh... and this speed test is absolutely free of ads! Indicates the delay a small packet of data requires to make a round-trip from your computer to the nPerf server. The shorter the delay, the most reactive is your connection.

A well-tested and proven component that is embedded on tens of thousands of websites worldwide. Our speed test component is used by millions of end-users every month in our own apps as well as our clients. Our Speedchecker HTML5 technology does not require any browser plug-ins and is, therefore, available across more platforms such as PCs, Macs, Android, iOS.

We can provide custom, bespoke designs to meet your design specifications and to fit in with your site or application design.

A comprehensive suite of network testing solutions, from VoIP and Bandwidth Quality testing to worldwide edge-to-edge deployments. VoIP & Video Quality testing is essential to maintaining the user experience across VoIP applications, such as voice calls and video conferencing. Conventional "speed" tests are meaningless without understanding the testing protocol. Bandwidth quality is the key to solving user experience issues. Automated testing provides a seamless and secure way to gather key network performance data across single and multi-edge networks. Regardless of the application, the user experience is everything. Configure in-depth tests to ensure a network is fit for purpose. Determine if the capacity of a connection is adequate for the load being expected of it. Even large capacity connections can be over-subscribed.
