Cache Slow Shortcodes With a Wrapper Shortcode
Adds a [cached] shortcode you wrap around any slow shortcode or content, such as [cached ttl="3600"][some_feed][/cached]; its output is stored for the time you choose and served from cache after that.
Snippet Library
Performance snippets for WordPress
Snippets that make WordPress lighter and faster: remove emoji scripts and embeds, control the Heartbeat API, limit revisions and load scripts only where they are needed. For developers and site owners chasing better Core Web Vitals.
Cache-Busting Versions Based on File Changes
Replaces the version number on your theme's and plugins' CSS and JavaScript URLs with the file's last-modified time, so browsers and CDNs cache files for a long time but always fetch a fresh copy right after you change one.
Delay Third-Party Scripts Until the Visitor Interacts
Holds back the scripts you list (chat widgets, heatmaps, social widgets) until the visitor first scrolls, taps, clicks or presses a key, or after a timeout, so they no longer slow down the initial page load.
Fast 404 for Missing Images, Scripts and Styles
Answers requests for missing images, CSS, JavaScript and font files with a tiny 404 instead of loading a full theme page, saving server time.
Keep Speculative Loading Away From Cart, Checkout and Account Pages
Tells WordPress's built-in speculative loading (prefetching pages on hover) to skip cart, checkout and account pages, which are personal, never cached and expensive to build, so hovering over their links no longer costs server time.
Log Pages That Run Too Many Database Queries
Records front-end URLs that run more database queries than a limit you set, with the query count and load time, and lists the worst offenders under Tools > Heavy Pages.
Log Slow Outgoing HTTP Requests
Times every request your site makes to other servers (update checks, APIs, license servers) and records the ones slower than a second under Tools > Slow HTTP Calls, so you can find what is holding up page loads.
Server-Timing Header for Administrators
Adds a Server-Timing header with PHP time, database query count and peak memory to pages viewed by administrators, so you can read the numbers in your browser's developer tools Network tab.
Site Health Check for Compression and Browser Caching
Adds a Site Health test that requests your homepage and one of your theme's stylesheets and reports whether text files are compressed (gzip or Brotli) and whether static files get long browser cache lifetimes.
Skip Loading Translations on English Sites
Stops WordPress, plugins and themes from loading translation files on the front end (or everywhere) to save memory and time on sites whose visitors read English anyway, with a list of text domains to keep.
Skip Slow Site Health Tests
Removes the Site Health checks that make HTTP requests back to your own site, which are slow or time out on some hosts.
