This helps reduce server load and improve page load times.<\/li>\n\n\n\n<li><strong>Smart Cache Invalidation<\/strong> &#8211; Smart cache invalidation automatically clears and updates cached content that is related to a page that you have just purged. It ensures that visitors always see the latest version of your site without manually purging caches.<\/li>\n\n\n\n<li><strong>Cookie and Device Aware Caching<\/strong> &#8211; Page Speed Boost (PSB) creates separate cache files for versions on your site on mobile and tablet, to offer optimal speed and performance regardless of the device of your site visitors.<\/li>\n\n\n\n<li><strong>Browser Caching<\/strong> &#8211; Browser caching stores frequently used website resources (e.g., images, scripts) in a visitor&#8217;s browser, Page Speed Boost (PSB) will set the appropriate caching headers for you automatically, so the browser caching occurs without any problems and users are served with content faster within the session.<\/li>\n\n\n\n<li><strong>Automatic Cache Warmup<\/strong> &#8211; Automatic cache warmup ensures that caches are pre-filled with the most important content, improving the initial loading speed of your website.<\/li>\n\n\n\n<li><strong>Ignore Standard Parameters<\/strong> &#8211; Page Speed Boost (PSB) will ignore your UTM parameters by default, utilizing your optimization resources in the most efficient way.<\/li>\n<\/ul>\n\n\n\n<p><strong>CDN<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>GZIP and Brotli Compression<\/strong> &#8211; GZip and Brotli are compression algorithms that reduce the size of web resources (e.g., HTML, CSS, JavaScript) before they are sent to the browser, resulting in faster load times.<\/li>\n\n\n\n<li><strong>Global CDN<\/strong> &#8211; A global CDN distributes your website&#8217;s content across multiple servers worldwide. This reduces latency and ensures fast content delivery to visitors, regardless of their location.<\/li>\n\n\n\n<li><strong>HTTP\/3 Compatibility<\/strong> &#8211; Page Speed Boost (PSB) optimizes your website to take advantage of the HTTP\/2 protocol, which enables faster and more efficient communication between the browser and server.<\/li>\n<\/ul>\n\n\n\n<p><strong>Fonts<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Optimized Font Rendering<\/strong> &#8211; The browser initially displays the text using a fallback font. Then, as soon as the web font is fully loaded, it swaps the text to use the desired web font. This approach is designed to reduce the time users spend looking at either an unstyled text or a blank space.<\/li>\n\n\n\n<li><strong>Deferred Font Loading<\/strong> &#8211; Deferred font loading delays the loading of non-essential fonts until after the main content has loaded, improving initial page load times.<\/li>\n<\/ul>\n\n\n\n<p><strong>Image Optimization<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lossy Compression<\/strong> &#8211; The images are compressed, keeping 80% of its quality so that the visual quality of the image is preserved, while it greatly decreases the size of the image.<\/li>\n\n\n\n<li><strong>Lazy Loading of Images<\/strong> &#8211; Lazy loading prioritizes the images you are currently viewing, saving up bandwidth and improving content delivery.<\/li>\n\n\n\n<li><strong>Lazy Loading of iframe<\/strong> &#8211; Lazy loading delays the loading of iframes, and videos (automatically detecting YouTube videos) until they come into the viewport, saving bandwidth and improving page performance.<\/li>\n\n\n\n<li><strong>Lazy Loading of Videos<\/strong> &#8211; Lazy loading delays the loading of videos (automatically detecting YouTube and Vimeo videos) until they come into the viewport, saving bandwidth and improving page performance.<\/li>\n\n\n\n<li><strong>Lazy Loading for Background images<\/strong> &#8211; Delays the loading of background images until they come closer to the viewport, which gives you an additional boost in performance.<\/li>\n\n\n\n<li><strong>WebP Conversion<\/strong> &#8211; WebP is a modern image format that offers better compression and quality than traditional formats like JPEG and PNG. Page Speed Boost (PSB) converts images to WebP for faster loading.<\/li>\n<\/ul>\n\n\n\n<p><strong>HTML<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>HTML Minification<\/strong> &#8211; HTML minification removes unnecessary code and whitespace from HTML files, reducing their size and improving page load times.<\/li>\n\n\n\n<li><strong>HTML Compression<\/strong> &#8211; HTML compression uses compression algorithms to reduce the size of HTML files for faster delivery to the browser.<\/li>\n\n\n\n<li><strong>Preloading and Prefetching<\/strong> &#8211; Upon hover on a link on an already optimized page, Page Speed Boost (PSB) preloads the page for optimal speed performance.<\/li>\n<\/ul>\n\n\n\n<p><strong>CSS<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>CSS Combining<\/strong> &#8211; CSS combining merges multiple CSS files into a single file, reducing the number of HTTP requests and speeding up page loading.<\/li>\n\n\n\n<li><strong>Generate Critical CSS<\/strong> &#8211; Above-the-fold critical CSS is the CSS required to render the visible part of a webpage. Page Speed Boost optimizes the delivery of critical CSS for faster rendering.<\/li>\n\n\n\n<li><strong>CSS Minification<\/strong> &#8211; CSS minification removes unnecessary characters and whitespace from CSS files, reducing their size and improving load times.<\/li>\n\n\n\n<li><strong>CSS Compression<\/strong> &#8211; CSS compression further reduces the size of CSS files using compression algorithms like GZip or Brotli.<\/li>\n<\/ul>\n\n\n\n<p><strong>JavaScript<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Advanced Resource Loader<\/strong> &#8211; The resource loader rearranges the way resources are fed to the main thread. This is done to take advantage of modern CPU\u2019s multi-core nature by offloading tasks away from the main thread.<\/li>\n\n\n\n<li><strong>Deferred Loading<\/strong> &#8211; Deferred loading delays the loading of non-critical JavaScript files, allowing the main content to load first for a faster initial page rendering.<\/li>\n\n\n\n<li><strong>JS Compression<\/strong> &#8211; JS compression is a technique that further reduces the size of JavaScript files by applying data compression algorithms, such as GZip or Brotli, to the code. Unlike minification, which focuses on removing unnecessary characters, compression reduces the file size by encoding the code in a more compact format.<\/li>\n\n\n\n<li><strong>JS Minification<\/strong> &#8211; JS minification is the process of removing unnecessary characters and whitespace from JavaScript code without altering its functionality. This results in a smaller file size, which can significantly improve the load time of web pages.<\/li>\n<\/ul>\n\n\n\n<p>After purchasing and enabling on the environment of choice via the User Portal, the <em>WP Engine Page Speed Boost<\/em> WordPress plugin will be installed automatically.<\/p>\n\n\n\n<a name=\"Settings\"><\/a>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Enable<\/h2>\n\n\n\n<div style=\"color:#32373c;background-color:#00d1b2\" class=\"wp-block-genesis-blocks-gb-notice gb-font-size-18 gb-block-notice\" data-id=\"10de4b\"><div class=\"gb-notice-title\" style=\"color:#fff\"><p>NOTE<\/p><\/div><div class=\"gb-notice-text\" style=\"border-color:#00d1b2\">\n<p>After purchasing a license, we highly recommend enabling and testing in a <a href=\"https:\/\/wpengine.com\/support\/environments\/\">Staging or Development environment<\/a> first. <em>This will be used to test compatibility rather than performance scores.<\/em><\/p>\n<\/div><\/div>\n\n\n\n<p>To enable Page Speed Boost on an environment:&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>From the <a href=\"https:\/\/my.wpengine.com\/sites\">User Portal<\/a>, choose <strong>Products <\/strong>in the main sidebar menu<\/li>\n\n\n\n<li>Click <strong>Page Speed Boost<\/strong> under <strong>Your products<\/strong>\n<ul class=\"wp-block-list\">\n<li>Access this page directly at: <a href=\"https:\/\/my.wpengine.com\/products\/page_speed_boost\">https:\/\/my.wpengine.com\/products\/page_speed_boost<\/a><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"636\" src=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-settings-1024x636.png\" alt=\"Screenshot of the Products page in the WP Engine User Portal showing the button to manage Page Speed Boost\" class=\"wp-image-125224\" srcset=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-settings-1024x636.png 1024w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-settings-300x186.png 300w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-settings-768x477.png 768w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-settings-1536x954.png 1536w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-settings-1500x931.png 1500w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-settings.png 1952w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>Click <strong>Select environments<\/strong><\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"608\" src=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-select-environments-1024x608.png\" alt=\"Screenshot of the Page Speed Boost page in the WP Engine User Portal showing the initial button to add Page Speed Boost to environments\" class=\"wp-image-125225\" srcset=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-select-environments-1024x608.png 1024w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-select-environments-300x178.png 300w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-select-environments-768x456.png 768w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-select-environments-1536x912.png 1536w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-select-environments-1500x890.png 1500w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-select-environments.png 1860w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<ol start=\"4\" class=\"wp-block-list\">\n<li>(Optional) It&#8217;s recommended to test Page Speed Boost on a Staging or Development environment before applying it to Production.

Purging this cache can help with visual discrepancies and displaying recent updates.<\/p>\n\n\n\n<p>To purge Page Speed Boost cache when logged into your website:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Locate <strong>Page Speed Boost<\/strong> in the top menu bar of the wp-admin<\/li>\n\n\n\n<li>Select the option you would like to use:\n<ul class=\"wp-block-list\">\n<li> <strong>Purge Entire Cache<\/strong>: Select this option to purge the cache for the entire website. <em>This option is visible from both the front end and the wp-admin area of your website.<\/em><\/li>\n\n\n\n<li><strong>Purge Current Page:<\/strong> Select this option to delete the page you are currently viewing from the cache. This means your website visitors will immediately see the updated content, however, it will not be optimized until Page Speed Boost prepares the newly optimized content. Usually, this takes between a few seconds to a few minutes. <em>This option is only visible from the front end of your website.<\/em><\/li>\n\n\n\n<li><strong>Invalidate Current Page:<\/strong> Select this option to mark the cached content on the page you are currently viewing as &#8220;stale,&#8221; but keep serving it until newly optimized content is available. As a result, visitors will always see optimized content, even though it may be outdated for a short while. <em>This option is only visible from the front end of your website.<\/em><\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"281\" src=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-wpadmin-cache-links-1024x281.png\" alt=\"Page Speed Boost wp-admin top bar menu options\" class=\"wp-image-125195\" srcset=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-wpadmin-cache-links-1024x281.png 1024w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-wpadmin-cache-links-300x82.png 300w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-wpadmin-cache-links-768x211.png 768w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2024\/07\/page-speed-boost-wpadmin-cache-links.png 1210w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Page Speed Boost cache can also be cleared from the User Portal: <\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>From the <a href=\"https:\/\/my.wpengine.com\/sites\">User Portal<\/a>, choose <strong>Products <\/strong>in the main menu<\/li>\n\n\n\n<li>Click <strong>Page Speed Boost<\/strong> under <strong>Your products<\/strong>\n<ul class=\"wp-block-list\">\n<li>Access this page directly at: <a href=\"https:\/\/my.wpengine.com\/products\/page_speed_boost\">https:\/\/my.wpengine.com\/products\/page_speed_boost<\/a><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Next to the environment, click the 3 dot menu icon<\/li>\n\n\n\n<li>Select <strong>Clear caches<\/strong><\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"453\" src=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2023\/10\/psb-cache-user-portal-1024x453.png\" alt=\"\" class=\"wp-image-124154\" srcset=\"https:\/\/wpengine.com\/support\/wp-content\/uploads\/2023\/10\/psb-cache-user-portal-1024x453.png 1024w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2023\/10\/psb-cache-user-portal-300x133.png 300w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2023\/10\/psb-cache-user-portal-768x340.png 768w, https:\/\/wpengine.com\/support\/wp-content\/uploads\/2023\/10\/psb-cache-user-portal.png 1180w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<div style=\"color:#32373c;background-color:#00d1b2\" class=\"wp-block-genesis-blocks-gb-notice gb-font-size-18 gb-block-notice\" data-id=\"10de4b\"><div class=\"gb-notice-title\" style=\"color:#fff\"><p>NOTE<\/p><\/div><div class=\"gb-notice-text\" style=\"border-color:#00d1b2\">\n<p>Page Speed Boost cache is included when using the <strong>Clear all caches<\/strong> buttons on the <em>Cache<\/em> page. <a href=\"https:\/\/wpengine.com\/support\/cache\/\">Learn more here.<\/a><\/p>\n<\/div><\/div>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Page Speed Boost Cache Warmup<\/h3>\n\n\n\n<p>The cache warmup feature preemptively optimizes and caches your pages without having to wait for traffic to a page for the cache to be updated.

Reducing the time it takes to establish a connection results in better performance. This setting is always enabled and we don\u2019t have an interface for it yet.<\/li>\n\n\n\n<li><strong>Minify resources<\/strong><br>Minification removes whitespace, comments and other unnecessary symbols from code files. This reduces file size, ensuring a faster download time.<\/li>\n\n\n\n<li><strong>Combine JavaScript (JS)<\/strong><br>Combining multiple JS files into a single file reduces the number of network requests the browser has to make. As a result, the browser finds and downloads everything it needs to render the page faster.<\/li>\n\n\n\n<li><strong>Combine CSS<\/strong><br>Combining multiple CSS files into a single stylesheet reduces the number of network requests the browser has to make. As a result, the browser finds and downloads everything it needs to style the page faster.<\/li>\n\n\n\n<li><strong>Combine CSS &gt; Merge screen and all media styles<\/strong><br>This option makes sure that NitroPack treats @media screen and @media all values the same. This prevents the creation of unnecessary CSS files.<\/li>\n\n\n\n<li><strong>Generate critical CSS<\/strong><br>Generate critical CSS means prioritizing the CSS responsible for styling above-the-fold content. Rendering above-the-fold content quickly improves a page\u2019s actual and perceived performance.<\/li>\n\n\n\n<li><strong>Generate critical CSS &gt; Remove @font-face rules from the critical CSS<\/strong><br>@Font-face rules specify a custom font, which can be loaded locally or from a server. Removing these rules results in slower font loading but faster First Meaning Paint (FMP).<\/li>\n\n\n\n<li><strong>Remove Unused CSS (RUCSS)<\/strong><br>RUCSS finds CSS rules that aren\u2019t used on the page and reduces them. By reducing unused CSS, this feature lowers the total number of bytes that have to be downloaded and helps browsers start rendering content faster.<\/li>\n\n\n\n<li><strong>Remove render-blocking resources<\/strong><br>By default, JavaScript and CSS files are render-blocking because browsers must load, parse and execute them before rendering the page. This can slow down page load significantly. NitroPack prevents this by rearranging and repositioning these blocking resources.<\/li>\n\n\n\n<li><strong>Remove render-blocking resources &gt; Use resource loader script<\/strong><br>Our resource loader rearranges the way resources are fed to the main thread. This is done to take advantage of modern CPU\u2019s multi-core nature by offloading tasks away from the main thread.<\/li>\n\n\n\n<li><strong>Remove render-blocking resources &gt; Delay loading of non-critical resources<\/strong><br>By default, NitroPack\u2019s Ludicrous Mode lazy loads JS execution until user interaction is detected. Lazy loading JS helps browsers start painting content (HTML, CSS) faster. In a lot of cases, this is crucial for avoiding page abandonment.<br><strong>Important Note<\/strong>: This setting is not a good fit for websites that heavily rely on JavaScript for displaying content. Before applying the setting on your site, we advise you to test it with the Test Mode.<\/li>\n\n\n\n<li><strong>Remove render-blocking resources &gt; Resource loading strategy<\/strong><br>This option lets you choose between prioritizing styles (CSS) or scripts (JS). Prioritizing styles is the safer option, while loading scripts first can provide better performance but isn\u2019t suitable for all websites.<\/li>\n\n\n\n<li><strong>Image lazy loading<\/strong><br>Lazy loading helps browsers only load the images that visitors are currently looking at. Doing this helps prioritize critical images over non-critical ones, resulting in a much lower initial page weight.<\/li>\n\n\n\n<li><strong>Image lazy loading &gt; Size images preemptively<\/strong><br>Preemptive image sizing tells the browser how much space to allocate for each image in advance (without using width and height attributes). As a result, the browser can render the page faster and avoid potential layout shifts.<\/li>\n\n\n\n<li><strong>iFrames Lazy load<\/strong><br>Again, lazy loading help helps browsers only load resources that visitors currently need. This option does the same thing, only for iFrames instead of images.<\/li>\n\n\n\n<li><strong>Image optimization<\/strong><br>Image optimization reduces image file size via compression. It also converts images to WebP while keeping the original image in place as a backup.<\/li>\n\n\n\n<li><strong>Image optimization &gt; Image quality<\/strong><br>This option lets you adjust the quality of optimized images. As you increase the number, the quality becomes better, but the image file also becomes larger. Allowed values are between 1 and 100. You can learn more about image quality and compression levels here.<\/li>\n\n\n\n<li><strong>Override font rendering behavior<\/strong><br>The font-display CSS rule determines how the browser should display fonts based on when they\u2019re downloaded. This option lets you override the default behavior by selecting from one of the five values below.<\/li>\n\n\n\n<li><strong>Override font rendering behavior &gt; Select font-display value<\/strong><br>You can choose between five values for the font-display rule &#8211; auto, block, swap (the default), fallback, optional. Each value can be helpful in specific cases. You can read more about the font-display values here.<\/li>\n<\/ol>\n\n\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Custom Settings<\/h3>\n\n\n\n<p>You can now make custom changes to settings for <strong>Page Speed Boost<\/strong>.
