Data efficient speed tests

This is an overview of data efficient speed tests. That is, the speed tests are displayed on the descending data efficiency score as determined by the standardized speed test. The data efficiency score is listed in brackets after the speed test.

Because there is a proportionate use between data efficiency and climate friendliness, we also show the CO2 labels in this overview.
