Joomla JCH Optimize Extension

JCH Optimize improves the performance of your website by performing several optimizations to the HTML page aimed at improving the Web Vitals measured by PageSpeed Insights, such as First Contentful Paint (FCP), Largest Contentful Paint (LCP), Speed Index (SI), Cumulative Layout Shift (CLS), Time to Interactive (TTI), and Total Blocking Time (TBT). These metrics attempt to quantify the quality of the user experience. JCH Optimize can improve these metrics to provide a better user experience and improve your PageSpeed scores.

##Optimizations Performed By JCH Optimize

JCH Optimize optimizes your pages by automatically performing some recommended strategies offered by PageSpeed, which include:

- Minify CSS and JavaScript files and the HTML. Unnecessary whitespaces and other characters are removed to reduce network payload sizes and script parse times.
- Eliminate Render-Blocking Resources. Inline critical JavaScript and CSS and defer all non-critical resources to prevent resources from blocking the first paint of your page.
- Defer offscreen images. Offscreen and hidden images are lazy-loaded after all critical resources have finished loading to lower Time To Interactive (TTI).
- Add Width and Height attributes to images. Set an explicit width and height on image elements to reduce layout shifts and improve CLS.
- Enable text compression. Boilerplate codes are placed in the .htaccess files at the site's directory root to instruct the server to serve text-based resources with compression (deflate or brotli) to minimize total network bytes.
- Preload critical resources. Automatically analyzes each page to identify critical resources to load with a high priority by HTTP/2 enabled servers to improve LCP time.
- Reduce initial server response. A Page Cache plugin is included in the package that integrates well with the JCH Optimize component and significantly reduces time-to-first-byte.

… and more.
