Delete Expired Transients vs PlugoSpeed

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.

PlugoSpeed is a WordPress performance plugin that combines page caching, asset optimization, and Core Web Vitals improvements in a single lightweight package. It generates static HTML cache files served directly from disk via Apache — bypassing PHP and WordPress on cached requests. In testing on a standard VPS, this approach achieves sub-50ms TTFB and PageSpeed scores of 95/100 on desktop. A React 18 dashboard provides real-time cache hit rates, bandwidth saved, and PageSpeed score tracking — no jQuery required. Core Features (Free) Static HTML Cache Pages are stored as static .html files on disk. Apache serves them directly — no PHP, no database, no WordPress bootstrap. Cache TTL is configurable (default: 24 hours). HTML Minification Removes unnecessary whitespace and comments from the final HTML output, reducing page size without affecting content or functionality. CSS Minification Minifies stylesheet files inline, reducing transfer size. Combine is intentionally disabled by default for HTTP/2 compatibility. JavaScript Defer Adds defer to non-critical scripts, improving Time to Interactive (TTI) and Largest Contentful Paint (LCP) scores on mobile. Image Lazy Loading Adds native loading="lazy" to images and iframes below the fold. Injects explicit width and height attributes to reduce Cumulative Layout Shift (CLS). Database Cleanup Scheduled cleanup of post revisions, auto-drafts, spam comments, and expired transients. Configurable schedule: daily, weekly, or monthly. Cache Preloading After purge, PlugoSpeed re-warms the cache automatically by walking your XML sitemap. Rate-limited to avoid server overload. Auto Cache Purge Cache is invalidated on post save, theme change, plugin activation, and WooCommerce stock/price updates. PageSpeed Dashboard Tracks your Google PageSpeed Insights score over time with a 30-day graph. Shows live cache hit/miss ratio, bandwidth saved, and page count. Pro Features Remove Unused CSS (RUCSS) Generates a per-page stylesheet containing only the CSS rules that are actually used. Eliminates render-blocking CSS from page builders and plugin stylesheets. Requires a PlugoPress API key. Critical CSS Inlines the above-the-fold CSS directly in , eliminating render-blocking for a faster LCP. Requires a PlugoPress API key. WebP Image Serving Automatically serves .webp versions of images to supported browsers, reducing image payload by 25–35% without quality loss.
