TTI stands for Time-to-Interactive, which refers to a metric used in web development and performance testing to measure the time it takes for a web page or application to become fully interactive and responsive to user input after the initial loading process is completed.
TTI is a crucial measurement in evaluating the user experience of a website or application, as it indicates the time required for a user to be able to interact with the webpage or perform actions such as clicking buttons, filling out forms, or navigating through the content.
The TTI metric takes into account multiple factors, including the time it takes to load all necessary resources, such as scripts, stylesheets, and images, as well as the time required for the browser to parse and execute these resources.
A low TTI is desirable, as it signifies that the webpage or application is optimized for quick user interaction, resulting in a smooth and responsive experience. On the other hand, a high TTI indicates that the page may have performance issues, resulting in a delay between user actions and system response.
Developers and performance analysts use TTI to assess and improve the performance of websites and applications, making adjustments to reduce load times, optimize resource delivery, and enhance overall user experience. By monitoring and optimizing TTI, developers can ensure that their web applications are optimized for speed and responsiveness, leading to greater user satisfaction and engagement.
