Speed Test Performance
TestSpeed measures the speed between your device and a test server using your device's internet connection. Several factors are important for a speed test.
Devices (phones, tablets, PCs, etc.) can have very different Wi-Fi and cellular radio capabilities. This means that even if you are using the same provider, you can get one TestSpeed result on one device and a different result on another. Some devices may not be able to measure the full speed of your internet service. It is also possible that your Wi-Fi modem does not support the full speed of your service.
TestSpeed servers may perform differently. In general, you get higher speeds from servers closer to you. We recommend testing on various test servers to get the most complete picture of your speed. TestSpeed has the world's largest test server network, which means you will always have the advantage of testing on a server close to your geographic location.
Other speed test services use different servers in different locations than TestSpeed, so there may be speed differences between test services.
Browsers (Chrome, Opera, Firefox, Explorer, Safari, etc.) have different capabilities and can give different results, especially on high-speed connections.
Before contacting your Internet Service Provider (ISP) or mobile operator, check if you are running ongoing downloads or other programs such as video chat that may consume your bandwidth. Close these and test again. If your Speedtest result still looks slow, restart your phone or computer, your modem and router. Then make sure that Quality of Service (QOS) features are not enabled on your router. If this doesn't solve the problem, there are a few more steps you can try.
Contacting your ISP or operator for help is a good step after completing these steps. Remember that on higher bandwidth connections (150 Mbps and above), you will need a higher quality router to keep up.
TestSpeed offers a network of more than 10,000 hosted SpeedTest servers worldwide so you always have test options. At the beginning of a test, Speedtest automatically selects a nearby server with a fast ping result to measure the maximum potential of your internet connection. You can always change the test server to a different server than the default selection, and we recommend testing on different servers to compare results.
By selecting a new server, you are changing the location or host of the server you are testing your internet connection with. In particular, many sites and streaming services may host their content on servers far from your current location, which can cause lower speeds and pings from these services.
Regardless of which server you choose, all tests run on TestSpeed reflect the speed of your connection from your current ISP or operator. Testing on a server hosted by an ISP or operator does not necessarily tell you how fast your connection will be if you sign up for the services they offer.
Your computer's firewall or a proxy server may be blocking communication on port 8080, which will limit the number of servers available for testing.
Why am I getting different speeds between my computer and my phone/tablet?
TestSpeed measures your real-time network connection, so tests performed a few minutes apart may vary slightly depending on network congestion and available bandwidth. If your TestSpeed results are significantly different, make sure you are:
Testing the same connection. If one device is on Wi-Fi and the other is not, you are testing the speeds of different connections.
Testing the same server. TestSpeed automatically selects the server to test based on ping, but you can also select a server to test.
Also, remember that there are significant differences in Wi-Fi and cellular radio quality and MIMO stream processing quality between devices. These variations can cause one device to give slower test results than another device or computer.
If you are asking this question, you are already tired of the constant buffering wheel. To get the best possible performance, download speeds usually need to be at least as fast as the following. Speed test values should be as follows.
