The company's speed tests are provided by Ookla, as are the tests at many other network providers. Not surprisingly, the highest consistent speeds were reported when I ran the tests offered by my ISP, AT&T. The results of the HTML5-based speed tests conducted at Bandwidth Place ranged from 5Mbps to 11Mbps, those at exhibited a similar range, and the Flash-based tests at ZDNet's Broadband Speed Test recorded speeds from 5.8Mbps to 11.4Mbps.
's download scores in both its single- and multithread tests exhibited a bit more range than those of Speakeasy's Speed Test, but they averaged about 11.2Mbps. After running several tests over a span of days, all of Speed Test's download results were within a few kilobits of 11.5Mbps. Of course, the services' tests may be consistently wrong. The most consistent test results were recorded at Speakeasy's Flash-based Speed Test and at 's HTML5-based tester. Others point out that multithread tests such as those used by Ookla ( and branded by many ISPs) don't represent real-world network traffic as well as single-thread tests. Many experts claim HTML5-based speed tests are more accurate than tests that use Java and Adobe Flash. Does the type of speed test make a difference?
