What is latency testing and why is it important for application performance?

Latency testing measures the time delay between a user action and the system’s response. It is important because high latency makes applications feel slow even if they don’t crash. By identifying delays in the network, server, or database, latency testing helps teams improve speed, user experience, and customer retention.
