As SSL uses the TCP as layer 4 protocol, all quality statistics of the TCP connection can be used for debugging. Additionally, the response time for the SSL handshake and the first encrypted SSL data response time is available too. | ||

A simple way to get an overview of the response time for skype servers is the '''IP statistics''' table. You can use the free text search for "skype" and select the the graph dialog: "tcp response time". This will present you the top IP addresses with a correlated name to skype and their tcp response time. | A simple way to get an overview of the response time for skype servers is the '''IP statistics''' table.
