Swift Performance will increase the loading speed of any WordPress website and provides an intelligent, modern caching system. You can even cache AJAX request, dynamic pages, and you can add exceptions (URL, page or content based rules).
Here are some of our most popular functions.
Caching. Page caching is working out of the box. It is compatible with WooCommerce, bbPress, Cloudflare and Varnish as well. It will boost your performance, improve SEO scores, and create a better user experience.
CSS and Javascript optimization. One of the most important thing for performance is optimize the delivery of static resources. Swift Performance not only combines and minifies the CSS files, but generates the Critical CSS for each page automatically. Also Javascripts (even inline scripts) can be combined, minified, and move to footer without any conflict. 
Huge combined javascript files may still be render blocking, however with our unique Async Execute solution, you can not only combine/minify the scripts, but you can run them individually as soon as a chunk has been downloaded – which provides incredibly fast JS execution, improves SEO scores and user experience.
Database Optimization. Keeping your database clean is extremely important for speed. Swift Performance has a built in DB Optimizer to clean expired transients, orphans, duplicated metadata, and spammy comments. You can also schedule every tasks. It has never been easier to keep your WordPress database clean.
Plugin Organizer. Plugins are a big part of WordPress, however sometimes not properly written plugins can cause performance issues. With Plugin Organizer you can disable plugins on certain pages, and let plugins run only where it is really necessary. You can set URL match, Frontend, Admin Pages, AJAX action rules and exceptions to get the best results.

Compute API. Compute API will speed up merging process and decrease CPU usage. Compute API also provides advanced JS minify, which should be used if default JS minification cause issues on your site. Compute API also provides Critical Font option, with that you can reduce font icon files’ size. This feature is essential for shared hosting users, as CPU usage is usually limited for shared hosting plans.
Critical Icon Fonts. With Critical Fonts feature you can select icons that you are actually using on your site, and generate customized icon font set from them. There is also a feature to search used icons in your theme/plugins, posts, options, etc. Once you selected the icons that you need, you can enqueue them with one click. If critical icon fonts are enqueued, the plugin will block the original version of the font CSS/font files.
Unlimited Image Optimizer. With Image Optimizer you can optimize every images on your site. It will scan the whole site, and pick up every image from themes, plugins and upload folder. Regarding that Image Optimizer is unlimited (no additional fees), you can save a considerable amount of money. You can select images individually, and run batch optimization. Default image quality can be specified in plugin settings, however you can overwrite it before starting the optimization on selected images.

Whitelabel. With whitelabel option you can re-brand Swift Performance. You can change the plugin name, description, author, even the database prefix for the plugin.
Remote Cron. Pro version provides a Remote Cron option. If you set the remote cron, our API server will call wp-cron.php and run WP cronjobs as real cronjobs.

Strange redirects 
If you have strange URLs in your analytics or you can see that the site redirects to an URL like this: 
https://www.yoursite.com/wp-content/cache/yoursite.com/desktop/unauthenticated/index.html 
This is caused by an improper order of htaccess rules. Probably you are using a force SSL or force www/non-www rule in htaccess. Please remove these rules from .htaccess, and insert them in Settings &gt; General &gt; Tweaks &gt; Custom htaccess.
My website broke 
It is possible that one or multiple files generate conflicts when those are merged and/or minified. If you notice that you website doesn´t show correctly, you might disable merge scripts and styles.
High CPU Usage 
While Swift is generating the cache, the CPU usage can be higher than usual. Swift is using more aggressive optimization than any other plugin on the market and it needs some CPU. Usually it isn’t an issue and CPU usage can be increased temporarily, but if it goes back to normal after prebuild finished, you don’t need to worry about it. 
However, for large sites on relatively small server it can cause too high CPU usage temporarily. Actually, when the server is using CPU it is always using 100%. High usage means the CPU was used for a longer period. 
If CPU usage is constantly higher you may need check the configuration. It is recommended to:
<ul>
<li>Enable Compute API: Settings &gt; General &gt; Compute API</li>
<li>Enable Optimize Prebuild Only: Settings &gt; Optimization &gt; General &gt; Optimize Prebuild Only</li>
<li>If you are not satisfied with Optimize Prebuild Only option, enable Optimize in background instead: Settings &gt; Optimization &gt; General &gt; Optimize in Background.</li>
<li>Setting a low number of threads as maximum: Settings &gt; Optimization &gt; General &gt; Maximum threads: set this to 2 or 1. 1 will make the pre-build a bit slow, so try 2 first.</li>
<li>Exclude third party CSS: Settings &gt; Optimization &gt; Styles&gt; Exclude 3rd Party CSS.</li>
<li>Disable Generate Critical CSS as generating Critical CSS is the most CPU intensive process: Settings &gt; Optimization &gt; Styles&gt; Generate Critical CSS.</li>
<li>Exclude third party JS: Settings &gt; Optimization &gt; Scripts &gt; Exclude 3rd Party Scripts.</li>
<li>Set Cache Expiry Mode to Action based, if you are not using nonce or anything that can expire on frontend: Settings &gt; Caching &gt; General &gt; Cache Expiry Mode: Action based.</li>
<li>Enable Prebuild Cache Automatically: Settings &gt; Caching &gt; Warmup &gt; Prebuild Cache Automatically.</li>
<li>Setup lower Limit prebuild speed (recommended to use on limited shared hosting): Settings &gt; Caching &gt; Warmup &gt; Prebuild Speed: Moderate (or Slow).</li>
<li>Exclude post types that you wouldn’t like to cache. Autoconfig should find most and exclude them automatically but you can can add them manually: Settings &gt; Caching &gt; Exceptions&gt; Exclude Post Types.</li>
</ul>
