ping also called latency or jitter . It is using stream technology to test your network connection quality by the closest server.
Online game players and remote terminal workers need low latency of the network. This page provides a fair way to test your network status. Less than 50 ms is perfect, less than 100 ms is still alright, and greater than 300 ms is awful. If the line in the chart is stable, your network is stable. If the line in the chart is unstable, your network is not stable. You can also look at the mean and standard deviation.
1000ms = 1 second
