Ping speed – is determined by measuring the round-trip time for a signal to travel from your device to a server and back, and is affected by factors such as distance, network congestion, and server response time. Ideally, ping speed should be between 1 ms to 50ms for a fast internet connection. slower is a higher number
Jitter – which measures the variation in ping speed – should be under 30ms or less for buffering video streaming. For text the jitter might not be noticed
