Swift Performance Pro is the paid edition of Swift Performance, a WordPress caching and performance plugin. It combines page and AJAX caching with controls for dynamic pages, CSS and JavaScript delivery, database maintenance, images, fonts, WooCommerce, and add-on loading.

Cache requests and optimize asset delivery

Page caching works out of the box. The cache also works with AJAX requests and dynamic pages, with exceptions based on URLs, pages, or content rules. Compatibility is listed for WooCommerce, bbPress, Cloudflare, and Varnish.

CSS and JavaScript tools can combine and minify files, generate Critical CSS for each page, and move JavaScript to the footer. Async Execute runs script chunks as they download. If merged or minified files cause show problems, disable script and style merging. Cache generation can temporarily increase CPU use, and larger sites on smaller servers may need optimization options adjusted.

Manage fonts, images, and database cleanup

The Compute API is designed to speed up merging and reduce CPU usage. It also includes advanced JavaScript minification for cases where default minification causes issues, plus a Critical Font option to reduce font icon file size.

Critical Icon Fonts lets you choose site icons and generate a customized icon font set. The plugin can search themes, extensions, posts, and options for used icons. After you select the icons, you can enqueue them with one click. When critical icon fonts are enqueued, the plugin can block the original font CSS and files.

The Pro Image Optimizer scans images in themes, extensions, and the uploads folder. Select images individually or run batch optimization. Set a default image quality in the plugin settings, then override it for selected images before optimization. Image optimization is described as unlimited with no additional fees.

The Database Optimizer, included in both Lite and Pro, cleans expired transients, orphaned and duplicated metadata, and spam comments. Pro adds scheduled database optimization so these tasks do not have to be run manually.

Control website tasks and plugin loading

Whitelabel settings let you change the plugin name, description, author, and database prefix. Once Remote Cron is configured, the plugin’s API server calls wp-cron.php to run WordPress cron jobs as real cron jobs.

Pro includes regular updates with new capabilities. Enabling the Beta tester option can provide updates more frequently.

For WooCommerce, Pro can disable cart fragments AJAX calls. Its session cache can cache and preload dynamic pages such as cart and checkout pages. The Plugin Organizer can disable plugins on selected pages, with rules for URL matches, frontend or admin pages, AJAX actions, and exceptions.

Install and configure

Install through the WordPress plugins screen or upload the plugin files to the /wp-content/plugins/ directory. Activate the plugin in WordPress and run the setup wizard to configure basic settings. Review caching, script and image optimization, database scheduling, WooCommerce options, and plugin rules before applying changes to the site.
