How to find a reliable network speed test
I'm sure it would, considering they all want to institute bandwidth caps, I was just speaking to what would be most useful.

Like how congested are interchanges, intra-city backbones, cross ocean links etc. Once you click on a local server the test begins automatically, measuring the download and upload speed of your connection, as well as the ping rate.

The highest download speed test result I recorded was However, the same test generated a download speed of 4. For the record, my ISP promises download speeds up to 12Mbps. I ran the tests in both Firefox and Google Chrome on a Windows 8. Conversely, the results of the upload tests at the various services were consistently at or just under 2Mbps. The exceptions were upload-test results at DSLReports.

I ran the tests at DSLReports. Others point out that multithread tests such as those used by Ookla Speedtest. Of course, the services' tests may be consistently wrong. After running several tests over a span of days, all of Speed Test's download results were within a few kilobits of The company's speed tests are provided by Ookla, as are the tests at many other network providers. The FCC's test also requires that you supply your street address. One of the dozen-or-so tests recorded a download speed of After conducting more than network speed tests from many different providers over the course of several days, I'm confident my ISP is delivering speeds approximating -- and perhaps exceeding -- those it promised when I signed up for the service.

Whether any of the speed tests I tried truly represent real-world network traffic is debatable. If you suspect you're paying for more bandwidth than you're actually getting, you needn't trust your ISP's test results to make your case -- especially if you happen to live in one of your service's dead zones. Once you click on a local server the test begins automatically, measuring the download and upload speed of your connection, as well as the ping rate.

The ping rate measures how long it takes for a tiny packet of data to reach and return from the test server, giving an indication of how responsive your connection is, which is critical for online gaming and services such as VoIP.

The site uses up to four simultaneous download streams to fully saturate the connection and get an accurate measurement of its potential. The upload speeds are then measured in a similar fashion.

The mobile app automatically collates your results, so you can tell if your connection speed is falling or improving over time. Thinkbroadband recently updated its long-established speed test, moving from a Java-based app to a new Flash-based service. Thinkbroadband asks users to enter their postcode and select their ISP before running a test, although neither piece of data is mandatory — the data is used to help map broadband speeds and rate the performance of ISPs.

The Thinkbroadband test uses six different HTTP streams to saturate the connection and measure download speeds, as opposed to Speedtest. The test checks to see all six threads are working, and restarts automatically if one thread fails, to ensure the accuracy of its results. Thinkbroadband delivers two different download results: The burst speed shows the maximum speed achieved throughout a small section of the test.

To complicate matters further, the site delivers burst and average speeds for single and six thread tests.
