Swift Performance Pro

Swift Performance Pro extends WordPress caching and performance tools with controls for picture and font optimization, scheduled tasks, WooCommerce, and add-on loading. Its cache works with pages, AJAX requests, and dynamic pages, with exceptions based on URLs, pages, or content rules. Compatibility is described for WooCommerce, bbPress, Cloudflare, and Varnish.

Configure caching and page assets

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. 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, plus a Critical Font option to reduce font icon file size.

Critical Icon Fonts lets you choose the icons used on a site and generate a customized icon font set. The add-on can search for used icons in themes, extensions, posts, and options. After selecting the needed icons, you can enqueue them with one click. When critical icon fonts are enqueued, the original font CSS and files can be blocked.

Optimize pictures and schedule database cleanup

The Pro Image Optimizer scans images in themes, plugins, and the uploads folder. You can select images individually or run batch optimization. Set default image quality in the plugin settings, then override it before optimizing selected images. The optimizer is described as unlimited, with no additional fees.

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

Manage website tasks and plugin loading

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

WooCommerce controls include disabling cart fragments AJAX calls. Session cache can cache and preload dynamic pages such as cart and checkout pages. The Plugin Organizer can disable plugins on selected pages, using URL matches, frontend or admin pages, AJAX actions, and exceptions.

The Pro edition receives regular updates that include new features. Its optional Beta tester setting can provide updates more frequently; Lite updates are described as compatibility updates.

Review site behavior after optimization

Cache generation can temporarily increase CPU use, particularly on large websites with limited server capacity. Merging or minifying files can also cause conflicts. If a page displays incorrectly, disable script and style merging and check the result.

Install and configure

Install Swift Performance Pro through the WordPress plugins screen or upload the plugin files to /wp-content/plugins/, then activate it in WordPress. Run the setup wizard for basic settings. Review caching, script optimization, image optimization, database scheduling, WooCommerce options, and plugin rules before applying changes to the site.
