Jul 21, 2020 · 2. How we measure server speed . Server speed is measured by testing its response time – the amount of time it takes for the server to respond to a request from a client. 3. What the server speed test reveals . The effective reach of the data center, hardware specs, server setup and their network planning . 4. Google’s server response time The bandwidth speed you get depends on lots of things, like network and Internet congestion, your computer's configuration, WiFi adapters used, others using Video On Demand or online gaming, the wiring in your location, etc. Therefore, we cannot guarantee a specific speed. Internet speed tests, like this one or the test found atSpeedTest.net , measure the latter, or the speed reaching the device running the test. These test results are often lower than your plan speed due to various factors outside your Internet provider's control, including WiFi conditions and device capabilities. An embedded experience specifically designed to be fast, clear and easy to use, Speedtest is available for Mac and Windows.

Check web hosting performance using our proprietary Server Speed Checker. Perform a server speed test to see your server response time around the globe.

Verify your server is externally accessible and properly configured using the Ookla Server Tester. More information on using the Ookla Server Tester can be found in the article Using the Ookla Server Tester . Our Speed Test automatically detects the optimal server host location for testing, which is not necessarily the closest server host. This is due to real-time network circumstances like number of hops, or current traffic load on each test server.

We recommend you to lower or stop all other internet activities during the test. In other cases the test results are less precise. Outputs: download speed - what speed are data from the testing server downloaded by; upload speed - what speed are data to the testing server uploaded by

Our Xfinity speed test dynamically uses a nearby server to test your internet speed. Other speed tests use a designated server instead of a dynamic one, which can skew your results. If the designated server is farther away than your Internet Service Provider’s (ISP’s) server, the results of your latency test may be inflated. This speed test checks the speed between your smartphone, tablet, computer, or other device and the internet. You can run the test through a cellular (mobile) network, a wired broadband connection, or your home Wi-Fi. A gateway speed test checks the speed between your AT&T Wi-Fi gateway and our network. "Raw Performance" is the speed when querying each nameserver directly "Resolver Simulation" simulates the algorithm of public DNS resolvers and shows the performance from the resolver's point of view "Uptime" shows the real uptime of DNS provider.
