Things that happends when user interacts with browser
When end-users interact with your website in a browser, they need to wait for a number of things to happen:
- Initialization: Resolving DNS, establishing TCP connection, proxy handling, and SSL/TLS handshake.
- Server Rendering: The server processes the request, fetches necessary data(fetch from cache,if not available fecth from DB, Compute), and renders the web page.
- Data Transfer: The HTML, CSS, JavaScript, and other resources are sent from the server to the browser.
- Page Rendering: The browser parses the resources, applies styles, executes JavaScript, and displays the page.
RAIL is a model
RAIL is a model that helps you avoid performance issues by setting general performance goals. RAIL stands for:
- Response (user interface): Tap to paint in less than 100ms;
- Animation: Layout rendering should take less than 16ms per frame;
- Idle: Use idle time to compute some work in chunks of 50ms;
- Load: The page should be fully loaded in less than 1000ms.
