 Jetpack Boost includes a growing number of separate features which can be turned on individually to improve your site’s performance. These include:
 
 * **Optimize CSS Loading**: This feature determines the most important CSS that your site needs to display your site’s initial content as quickly as possible, and embeds it directly into your site header.
+* **Page Cache**: This feature stores your website's pages as static HTML files, bypassing the need for dynamic generation. This means visitors receive pages faster, reducing wait times and improving overall site performance.
 * **Defer Non-Essential JavaScript**: This feature forces all of the JavaScript which is not deemed essential to displaying your site to load after your site’s main content has been loaded.
 * **Image CDN**: This feature automatically resizes images to a more appropriate size for your visitors' screens, converts them to modern image formats, and serves them from Jetpack's worldwide network of servers.
 * **Concatenate JS**: This feature reduces the size of your JavaScript resources, and automatically combines them into fewer files, allowing your site to load faster with fewer requests.
