Comparitech's speed test was a speed test which automatically detected your IP address and your internet service provider. Besides that it automatically selected a test server.
This speed test started with connecting, a download test, followed by an upload test. When the download test was finished, the ping time besides the download speed was shown.
When the test was finished the download speed varies often a little from the earlier given download speed. For this test the first download speed given was used.
Free to use
Comparitech was free, there were no ads so the speed test earns 1 point.
Easy to use
Comparitech's speed test didn't pass the WCAG 2.0 Level A test.
The speed test could be started with 1 click, so 1 point is earned. Note that the website used cookies, there was small banner which informs the user regarding the cookies. It wasn't necessary to accept these cookies (or close the banner) to start the test.
Accuracy and consistency
Tested with a clean version of Chromium, throtteld at 30Mbps (30720 kbps) the following measurements were done.
Test Server: Amsterdam, The Netherlands (2)
- 34.10Mbps (21 seconds)
- 33.99Mbps (21 seconds)
- 33.99Mbps (21 seconds)
- 33.99Mbps (21 seconds)
- 33.99Mbps (21 seconds)
Tested with a clean version of Firefox, throtteld at 30Mbps (Wi-Fi) the following measurements were done.
Test Server: Amsterdam, The Netherlands (2)
- 33.98Mbps (21 seconds)
- 33.93Mbps (21 seconds)
- 33.87Mbps (21 seconds)
- 33.88Mbps (21 seconds)
- 33.86Mbps (21 seconds)
That gave an average of 34.0Mbps and a standard deviation of 0.07Mbps for the downloadspeed. The average and standard deviation for the time required were respectively 21 seconds and 0 seconds.
Note that based on the Chromium measurements the average download speed is 34.0Mbps with a standard deviation of 0.05Mbps. While the Firefox measurements gives an average download speed of 33.9Mbps with a standard deviation of 0.05Mbps.
Based on the measurements noted above you might conclude that the throttling speed of Firefox compared to the throttling speed of Chromium is not significant different.
