 The frequency when the test will be automatically triggered can be adjusted by setting the value `scan_interval` in seconds.
 
+Parallel streams can help in some situations. As TCP attempts to be fair and conservative, you may consider increasing the `parallel` attribute. Use this value with careful and refer to Iperf3 man page for more information.

 You can use the service `sensor.iperf3_update` to trigger a manual speed test for all sensors. Iperf3 has its own service call that allow to perform a speed test on a particular entity.
