Speed TestTest your download, upload and latency from a mobile phone up to optical fiber, and everything between. This test is pure HTML5 This test requires your browser's full attention for accurate results. Run the test when your network is quiet, and don't switch to other applications or change browser tabs during the test. A few Windows security and privacy software packages can block the test or slow the browser.
Participating ISPs
Contribute a server over 30 more servers are paid for by DSLReports. See the map 72951748 Welcome to the speed test that tests internet speed not just speed to your ISP.
More..The TL;DRThis test needs a modern (recent) browser. If it hangs under Windows, please temporarily disable any browser extentions or security software that is likely to be a culprit. If you find windows add-ons that use excessive CPU during the test, or break the test, please please tell us about it. There is a FAQ on error numbers that includes other tips. Please wait for the test to finish, and do not switch browser tabs. The results button will show you how your result compares to others from your ISP. If it works well for you, please tell other people. News: Leo Laporte recommended this test over others on 19th July, on his weekly live show The Tech Guy. Thanks Leo!What is a speed test?A speed test checks the maximum speed of your connection to a remote server on the internet. This test runs in your browser. It does a multiple stream download and upload to servers it determines may be closest to your location. The test should take no longer than one minute to complete. Speeds are quoted in megabits per second (1 million bits per second) or kilobits per second (1000 bits per second) of data. The speed test attempts to take your network connection to its maximum speed. This can be limited by several factors including the distance to the test servers, the operating system in use, the traffic en-route, and of course any congestion or wiring problems close to your location. The servers are dedicated to speed testing and monitored for performance. They are currently capable of running from 300 megabit for the smaller servers to over 2 gigabit for the faster servers. Generally the ultimate speed limit is not the server speed but the distance to the server. The closer to the server the higher speeds can be obtained by the client operating system. About geo-locationThe geo-location function - that button at the end of the row - allows you to store a location (long/lat) along with your speed result. This information is NOT shared with third parties. It will be used only to build fully anonymised speed maps. You can delete the location from our database by clicking the button again (green indicates a fix for your IP address is stored). What are speeds like in 2016?
What is a good Ping?Ideal ping would be less than 1 millisecond. Since the laws of physics dictate that the speed of light in a vacuum is about 186 miles per millisecond, one can calculate the absolute minimum latency for any point to point link. Cellphone data and Satellite networks can have very high ping time, although 4G can be competitive with ADSL/Cable, ping on 3G and GPRS can be 500 milliseconds or more.
Why is this the best speed test?
There are a wide variety of speed tests. Java, Flash, HTML5 with nifty graphics. ISP branded tests. Why do we feel this is the best?
