Web performance optimization occurs by monitoring and analyzing the performance of your web application and identifying ways to improve it. Web applications are a mixture of server-side and client-side code. Your application can have performance problems on either side and both need to be optimized. The client side relates to performance as seen within the web browser. This includes initial page load time, downloading all of the resources, JavaScript that runs in the browser, and more. The server side relates to how long it takes to run on the server to execute requests. Optimizing the performance on the server generally revolves around optimizing things like database queries and other application dependencies. 1. Code your site for mobile-first quality and speed 2.
