The ISP in use delivers a download speed of 50Mbps. This test gives an indication of the standard deviation in the test results.

All tests have been done with Firefox on Linux. All speed tests are opened in a separate tab. The tests are done in rounds. Each speed test is tested once per lap. The first test is with Bandwidth Place, the second test is with Comparitech and so on. After testing the Xfinity xFi Speed Test (the last speed test to be tested), the second round begins with the same tests. There are a total of five test rounds.
