Remember, if you deliver the resources 150 ms early, it takes 150 ms early for these resources to create a meaningful image and create a productive experience for the user. Below, you can see the measurement data made by emulating the Motorola G4 Mobile device in a 3G connection environment with the WebPageTest.org tool for our Icerikbulutu.com website. At the same time, you can also examine how much time each step takes, specific to the source. Core Web Vitals: New Google Pages Experience and Speed Performance Ranking Factors Major items that I frequently encounter in my website speed performance tests and that take time in the delivery of resources are.
DNS Lookup & Prefetch TCP Connection TLS & SSL Negotiation TTFB HTML preconnect preload Async & DEFER A request is created for the required resources to the server, DNS Lookup is performed and the TCP Connection Country Email List connection is opened. Once the connection is established, TLS & SSL verification is performed. The HTML source is called from the Server and the HTML is parsed with the received response. In this process, the most prioritized resources by the browser are CSS and JS resources. Then multimedia resources are loaded.
If the browser encounters a render-blocking resource during the process of rendering the web page, which are generally CSS and JS resources without async and defer applied, the HTML parsing and rendering process is paused and the CSS and JS resources are downloaded + parsed + processed/rendered. Below, the purpose of ASYNC and DEFER operations for CSS and JS resources that are render-blocking is explained. Core Web Vitals: New Google Pages Experience and Speed Performance Ranking Factors source: www.josefzacek.cz Important!: You should DEFER JS resources, but after the DEFERRED JS resources are Executed, if the interface shifts by adding a new frame to the user interface with the rendered JS resources, this will negatively affect the increase in the CLS value.
