From the user’s perspective, everything is simple. In the web browser, click on the measurement button and wait. Before starting the speed test, it is important to deactivate all tasks, applications and devices that could use the capacity to connect to the Internet. The results would be affected by that and you would not find out anything, or the conclusions would not have the required notification value.
The technical solution and the background of the speed test itself are complex, but to explain it in a few words and very simplistically, the test simulates a situation in which you download or upload data. The measured values are calculated depending on the speed of these transmission. You can test the speed of up to 30 test servers located in geographically different locations.
