Latency is one of the most critical performance metrics for any relay system, especially for real-time communication and interactive applications. It refers to the time delay between sending a signal from the source to the relay and receiving it at the destination. High latency can cause delays in communication, which can negatively impact services like VoIP (Voice over Internet Protocol), video conferencing, and online gaming. Therefore, minimizing latency is crucial for maintaining seamless communication and ensuring smooth user experiences. In systems where real-time data processing is essential, such as in financial trading platforms or autonomous vehicles, even milliseconds of delay can result in significant issues.
