Swift Performance Pro

Swift Performance Pro is the paid edition of Swift Performance, a WordPress caching and performance extension. Its core tools include page and AJAX caching, rules for dynamic pages, CSS and JavaScript optimization, database cleanup, add-on management, and a setup wizard. Pro includes controls for pictures, fonts, scheduled tasks, WooCommerce, and site administration.

Cache requests and process assets

The cache supports pages, AJAX requests, and dynamic pages, with exceptions based on URLs, pages, or content rules. Listed compatibility includes WooCommerce, bbPress, Cloudflare, and Varnish.

CSS and JavaScript tools can combine and minify documents, generate Critical CSS for each page, and move JavaScript to the footer. Async Execute runs script chunks as they download. The Compute API is designed to speed up merging and reduce CPU use. It also offers advanced JavaScript minification for cases where default minification causes issues.

Cache generation can temporarily increase CPU use. Larger websites on smaller servers may need to adjust optimization settings if usage stays high after cache prebuilding.

Optimize images, fonts, and database tasks

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

The Critical Font option can reduce the size of font icon files. Critical Icon Fonts lets you select site icons and generate a customized icon font set. The plugin can search themes, extensions, posts, and options for used icons. After selecting the icons you need, enqueue them with one click; when critical icon fonts are enqueued, the original font CSS and files can be blocked.

Both Lite and Pro include a Database Optimizer for expired transients, orphaned or duplicated metadata, and spam comments. Pro adds scheduled database optimization, so these cleanup tasks do not need to be started manually each time.

Configure cron, WooCommerce, and plugin loading

After Remote Cron is configured, the plugin's API server can call wp-cron.php and run WordPress cron jobs as real cron jobs. Whitelabel settings let you change the plugin name, description, author, and its database prefix.

Pro can disable WooCommerce cart fragment AJAX calls. Its session cache can cache and preload dynamic pages such as the cart and checkout.

The Plugin Organizer can disable plugins on selected pages so they load only where needed. Rules can match URLs, frontend or admin pages, and AJAX actions, with exceptions.

Pro includes regular updates with new capabilities. Its optional Beta tester setting can provide updates more frequently. Lite updates are described as compatibility updates.

Install and configure

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