Round Trip Time (RTT)

Round Trip Time (RTT) is the duration it takes for a data packet to travel from your device to a server and back again. Think of it like sending a message through a courier: RTT measures how long it takes for the courier to deliver your message and return with a response. It’s an important metric in internet communication, affecting how quickly websites load or data is transferred. Lower RTT values mean faster communication, while higher values can cause delays or lag. RTT is typically measured in milliseconds (ms).
