What the test will show

Check delivery of numbered WebRTC messages: missing messages to the server, missing replies and replies that arrive late.

How to take the test

  1. Close downloads and select duration.
  2. Wait for the WebRTC connection to be established.
  3. Compare losses and delays; save the detailed result.

How to understand the result

Message delivery of a specific WebRTC channel is measured. This is not a counter of each IP packet or a game server ping.

Compare multiple runs under the same conditions. Then change one factor: connection, device, or setting. If the symptom persists, repeat the test on another device and save the conditions - this will help to more accurately describe the problem to support.
