A fast ping means a more responsive connection, especially in applications where timing is everything (like video games). Ping is measured in milliseconds (ms). Anything under 20ms is generally considered to be very good. 2ms is about as low as you're going to get.4 Dec 2018
Is 20ms latency bad?
Network latency is how long it takes for data to travel between its source and destination. A good latency is a ping rate of below 150 milliseconds. 20ms is considered to be great.
