Delete Expired Transients vs StaticDelivr

Delete old, expired transients from the WordPress options table (wp_options), to prevent them from bloating your database and even slowing down your website. Unless you are using an object cache (like memcached), WordPress stores transient records in the options table. Many transients are given an expiration time, so in theory they should disappear after some time. In practise, because old transients are only deleted when requested again after they’ve expired, many transients stay in the database. After a while, there can be thousands or even millions of expired transients needlessly taking up space in your options table, depending on what your plugins are doing. Delete Expired Transients schedules a daily task to delete any expired transients from the options table. It performs this operation with a single SQL query, and then runs a second query to find any orphaned expiration records and deletes them too. There are a few other plugins around that clean up expired transients. This one is written for fast performance, set-and-forget scheduled housekeeping, and maximum compatibility. It uses the PHP time to determine whether transients are expired, not the database time (which can be different). It does only one job, and it does it well with the minimum of resources. Now optimised for WordPress Multisite.

StaticDelivr CDN is a lightweight and powerful plugin designed to improve your WordPress site’s performance. By rewriting theme, plugin, core file resource URLs, optimizing images, and proxying Google Fonts through the StaticDelivr CDN, the plugin ensures faster loading times, reduced server load, better privacy, and an improved user experience. StaticDelivr is a global content delivery network (CDN) that supports delivering assets from various platforms like npm, GitHub, and WordPress. By leveraging geographically distributed servers, StaticDelivr optimizes the delivery of your static assets such as CSS, JavaScript, images, and fonts. Key Features Smart Asset Detection: Automatically detects which themes and plugins are from wordpress.org and only serves those via CDN. Custom themes and plugins are served locally. No configuration needed! Failure Memory System: If a CDN resource fails to load, the plugin remembers and automatically serves it locally for 24 hours. No more repeated failures! Automatic URL Rewriting: Automatically rewrites URLs of enqueued styles, scripts, and core files for themes, plugins, and WordPress itself to use the StaticDelivr CDN. Image Optimization: Automatically optimizes images with compression and modern format conversion (WebP, AVIF). Turn 2MB images into 20KB without quality loss! Google Fonts Privacy Proxy: Serve Google Fonts without tracking (GDPR compliant). A drop-in replacement that strips all user-identifying data and tracking cookies. Automatic Fallback: If a CDN asset fails to load, the plugin automatically falls back to your origin server, ensuring your site never breaks. Localhost Detection: Automatically detects development environments and serves images locally when CDN cannot reach them. Child Theme Support: Intelligently handles child themes by checking parent theme availability on wordpress.org. Separate Controls: Enable or disable assets (CSS/JS), image optimization, and Google Fonts proxy independently. Quality & Format Settings: Customize image compression quality and output format. Verification Dashboard: See exactly which assets are served via CDN vs locally in the admin panel. Failure Statistics: View which resources have failed and are being served locally, with option to clear cache. Compatibility: Works seamlessly with all WordPress themes and plugins — both from wordpress.org and custom/premium sources. Improved Performance: Delivers assets from the StaticDelivr CDN for lightning-fast loading and enhanced user experience. Multi-CDN Support: Leverages multiple CDNs to ensure optimal availability and performance. Free and Open Source: Supports the open-source community by offering free access to a high-performance CDN. Use of Third-Party Service This plugin relies on the StaticDelivr CDN to deliver static assets, including WordPress themes, plugins, core files, optimized images, and Google Fonts. The CDN uses the public WordPress SVN repository to fetch theme/plugin files and serves them through a globally distributed network for faster performance and reduced bandwidth costs. Service Terms of Use: StaticDelivr Terms Privacy Policy: StaticDelivr Privacy Policy How It Works StaticDelivr CDN rewrites your WordPress asset URLs to deliver them through its high-performance network: Smart Asset Detection The plugin automatically verifies which themes and plugins exist on wordpress.org: WordPress.org Assets: Served via StaticDelivr CDN for maximum performance Custom/Premium Assets: Automatically detected and served from your server Child Themes: Parent theme is checked. If the parent is on wordpress.org, assets load via CDN This means the plugin “just works” with any combination of wordpress.org and custom themes/plugins! Failure Memory System (New in 1.7.0!) The plugin learns from CDN failures and automatically adapts: First failure: Fallback fires, failure is recorded Second failure: Resource is blocked from CDN for 24 hours Auto-recovery: After 24 hours, resources are retried automatically Manual reset: Clear the failure cache anytime from settings This ensures that problematic resources (Cloudflare-protected images, auth-gated content, etc.) are handled gracefully without repeated failures. Assets (CSS & JavaScript) Original URL: `https://example.com/wp-content/themes/theme-name/version/style.css` Rewritten CDN URL: `https://cdn.staticdelivr.com/wp/themes/theme-name/version/style.css` This process applies to themes, plugins, and core files: Themes: Original: `https://example.com/wp-content/themes/twentytwentythree/1.0/style.css` CDN: `https://cdn.staticdelivr.com/wp/themes/twentytwentythree/1.0/style.css` Plugins: Original: `https://example.com/wp-content/plugins/woocommerce/assets/js/frontend/woocommerce.min.js` CDN: `https://cdn.staticdelivr.com/wp/plugins/woocommerce/tags/9.3.3/assets/js/frontend/woocommerce.min.js` Core Files: Original: `https://example.com/wp-includes/js/jquery/jquery.min.js` CDN: `https://cdn.staticdelivr.com/wp/core/tags/6.9/wp-includes/js/jquery/jquery.min.js` Images Original: `https://example.com/wp-content/uploads/2024/01/photo.jpg` (2MB) Optimized CDN: `https://cdn.staticdelivr.com/img/images?url=https://example.com/wp-content/uploads/2024/01/photo.jpg&q=80&format=webp` (~20KB) Google Fonts Original CSS: `https://fonts.googleapis.com/css2?family=Inter:wght@400;500;600&display=swap` Privacy Proxy: `https://cdn.staticdelivr.com/gfonts/css2?family=Inter:wght@400;500;600&display=swap` Original Font Files: `https://fonts.gstatic.com/s/inter/v20/example.woff2` Privacy Proxy: `https://cdn.staticdelivr.com/gstatic-fonts/s/inter/v20/example.woff2` This ensures faster delivery through StaticDelivr’s globally distributed network while protecting user privacy.
