How the upload speed test works
DirectSPEED is a provider-independent bandwidth test for all common Internet accesses. The upload test uploads a special uncompressed test file to our server. The upload time is measured precisely. The maximum speed is determined from these measured values.
During the DSL test, you should not perform any other activities or downloads on your computer in order not to falsify the measurement.
Virus scanners or firewalls can also have a negative influence on the measurement.
We recommend briefly deactivating these programs for the test in order to obtain a reliable test result.
Larger data packets are transferred during the speed test, so a data flat rate is recommended.
