| Pros | Page caching, minification and lazy loading in one place; Browser cache headers and database cleanup; Free, from the WordPress.org directory | Serves cached static HTML, reducing PHP load; Simple and expert modes; Cache preloading and automatic expiry of old files |
| Cons | Dynamic caching and Memcached are SiteGround-only; CDN premium tier depends on the hosting plan; Calls Google PageSpeed and Google Fonts services | No CSS or JavaScript minification; Cloudflare or other proxies can make the built-in test report false failures; Object cache support only applies when a persistent object cache is installed |
