The DSLReports speed test

https://www.dslreports.com/speedtest The DSLReports speed test 0 1/5 stars ★☆☆☆☆ Hans van der Graaf

In general, the DSLReports speed test is not a recommended speed test, mainly because it is hard to run this speed test. When this speed test runs the results are relative accurate, although there are more accurate speed tests. Besides that this speed test is very slow.

 

With an adverstised speed of 200 Mbps and an average measured internet speed of 204.5 Mbps, we conclude that the DSLReports speed test is a relative accurate speed test (Accuracy score: 81/100).

The DSLReports speed test is a realistic speed test. That is, this speed test measures your true internet speed.

The DSLReports speed test is owned by SilverMatrix9 Corp. The first occurence of the DSLReports speed test in the WayBack Machine is April 2000. Indeed, the DSLReports is an oldie.

Wikipedia has a page dedicated to DSLReports.

Pros

This DSLReports speed test has the following pros:

  1. DSLReports is an original speed test
  2. When the speed test completes they are relative accurate

Cons

This DSLReports speed test has the following cons:

  1. very sensitive to errors
  2. very slow

Sensitive to errors

The DSLReports speed test is a relative critical speed test in the sense that the test is aborted relatively easily.

As written at the homepage This test requires your browser's full attention for accurate results. Run the test when your network is quiet, and don't switch to other applications or change browser tabs during the test. A few Windows security and privacy software packages can block the test or slow the browser.

Error 7

Under linux we have tried the DSLReports speed test with different browsers (Google Chrome, Microsoft's Bing, Firefox and Vivaldi). In all cases we got "error 7" as a result. This despite the fact that the speed test had the browser's full attention.

Under Windows we got also error 7 when using the Firefox browser. The DSLReports speed test used to work fine under Windows with chromium based webbrowsers like Google Chrome, Microsoft's Bing and Vivaldi. However June 2024 even with these browsers -running at Windows- we were not able to run this speed test.

Losing focus: Error 24

When you switch tabs when running the speed test, you will get error 24. It is suggested that enabling web workers in the (advanced!) settings will solve this problem. That's indeed the case.

In summary: when this speed test works, it works fine, however it takes a long time (over a minute) to complete the test. Hence this speed test is not recommended.

When to use DSLReports

Running DSLReports is that hard that we advice you to use another speed test.

How we tested

We have tested the DSLReports speed test partly in a standardized way. Partly because we were not able to run the test, hence we based this review also on the following earlier performed tests:

  1. DSL Reports (2020)
  2. Accuracy check (2020)
  3. Updated accuracy check (2020)
  4. The ultimate speed test test 2021
  5. DSL Reports (2022)
  6. Two hunderd and one point six (2023)

Note that the accuracy score is based on the Two hunderd and one point six test.

The following results form the basis for this speed test review:

  1. Abort/pause possible: Unknown
  2. Ad-free: no
  3. Average download speed of 3 measurements: 204.5 Mbps
  4. Clear indication of the current focus: yes
  5. Correct back button behavior: Unknown
  6. Flesch Reading Ease score of the privacy policy: 44.21
  7. Number of ACheckers known problems: 29
  8. Number of cookies: 6
  9. Number of measured features: 3
  10. Number of Wave errors: 9
  11. Observatory score: 0
  12. Tingtun score: 92.48
  13. Total data use of 3 measurements: Not available
  14. Total time to complete 3 tests: 194 seconds (based on DSL Reports (2022))
