What is RTT (round-trip time)?
Round-trip time (also called RTT): The time it takes for a small message to travel from a sender to a destination and for the reply to return. It is a basic measure of network delay and is what the ping tool reports.
Round-trip time: an example
A ping reporting 45 ms means the round trip to the server and back took 45 milliseconds.
