Description: Query latency refers to the delay between sending a query to a server and receiving the corresponding response. This phenomenon is crucial in the realm of web performance optimization, as it directly affects user experience. High latency can result in prolonged loading times, which may lead to user frustration and ultimately loss of traffic to a website. Latency can be influenced by various factors, including the geographical distance between the client and the server, the quality of the internet connection, server load, and the efficiency of the code handling the queries. In an ideal environment, latency should be minimal, allowing online interactions to be fast and smooth. Latency measurement is commonly performed in milliseconds (ms), and it is considered a key indicator of web application performance. Therefore, managing and optimizing query latency is a fundamental aspect for developers and system administrators seeking to improve efficiency and user satisfaction on digital platforms.
