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.
What are speeds like in 2015?
Down/Up speeds megabit/second in 2015
|Fiber TTH ||950/950||500/500|
|Cable DOCSIS3 16x4 ||600/120||343/120|
|Cable USA typical ||50/30 ||20/5|
|ADSL ||25/5 ||8/1 |
ping time is 600ms+
|WISP (wireless ISP) ||50/50 ||20/5 |
|Phone 4GX |
trial phases only
|Phone 4G/LTE ||50/50 ||10/5 |
|Phone 3G ||3/1 ||2/1 |
|Phone E)GPRS (kilobit)||200/60 ||100/100|
|Phone GPRS (kilobit) ||80/20 ||40/14|
|There are many different standards hiding behind phone 4G/LTE/3G rates, peak and typical is different country to country|
What is a good Ping?
Ideal would be less than 1 millisecond. Since the laws of physics dictate the speed of light in a vacuum is about 186 miles per millisecond, one can confidently calculate the absolute minimum latency for any point to point link. Older cellphone data and Satellite networks can have very high ping time. 4G can be competitive with ADSL/Cable but ping on 3G and GPRS latency can be 500 milliseconds+.
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?
- We have the pedigree. 15 years ago we launched the very first popular broadband speed test. It was a Java applet and did a simple staged download and upload. Last time we checked it had logged over 150 million tests. One of the first ISPs to donate test servers the app depended on was a company called Speakeasy. The traffic must have made an impression on them because a few years later the CEO quit to start .. Ookla aka. speedtest.net.
- This is the worlds first multi-stream HTML5 speed test. Multi-stream testing overcomes the need for the speed test server to be physically very close to your location. It also represents the modern usage pattern of your internet link: someone is streaming netflix, something is downloading a patch, someone is using a VOIP phone. Of course if you want single stream testing you can set that in the handy preferences panel.
- This test does not require highly insecure and annoying Flash plug-ins or Java installs, nor does it require installation of an app. All your results, from any device, are together.
- The test works consistently as possible across all modern browsers. People use Kindles, Playstation4 browsers, SmartTVs, Linux, FreeBSD - just anything with a modern browser.
- Wide range of operating conditions: The test has been tuned to work accurately over satellite links, over laggy phone data links - but in the same 30s to 60s run time it will also measure gigabit capable connections.
- Your entire test history is kept for your use even if you are not a registered member. Members can delete their tests and the data is actually, really, gone.
- We do not have an interest in making ISPs look good! All test servers are located OUTSIDE your ISP in amazon and google data centers, the same ones that netflix and youtube use.
- Your data is private. We collect data in order to present anonymized statistics but do NOT send it outside dslreports.com or to your ISP. If that should ever change, it will be clearly indicated and opt-out will be available.
- This test does not piggy back a CDN (content delivery network) with an impressive list of cities but dodgy geo-location and shared servers. All test servers are dedicated to testing, are monitored, and are capable of delivering or accepting a total of over 20 gigabit/second 24/7. If the servers get close to any capacity ceilings then the number of people per minute testing is capped to keep results clean. (Your browser and PC probably cannot accept 20 gigabit/second but it is there!).
- We regularly log gigabit results from well connected research and corporate IP addresses using average PCs and browsers.
- The test has been exhaustively tuned and approved by regular ISP customers (members of this site) and this process continues. Our feedback forum is public, please use it to raise any concerns or ask anything. If you can dispute any claims in this awful list of boasts, please post!
