Measuring performance with the Navigation Timing API
Measuring and optimizing the client-side performance is essential for a seamless user experience, and this is critical for web 2.0 applications using AJAX.
Capturing vital information, such as the time taken for page load, rendering of the elements, and the JavaScript code execution, helps in identifying the areas where performance is slow, and optimizes the overall client-side performance.
Sometimes, third-party controls, images, and media content also cause degradation in the performance. Using Selenium WebDriver and various other tools together, we can measure the performance and eliminate the weaker content.
Navigation Timing is a W3C Standard JavaScript API to measure performance on the Web. The API provides a simple way to get accurate and detailed timing statistics natively for page navigation and load events. It is available on Internet Explorer 9, Google Chrome, Firefox, and WebKit-based browsers.
