PageSpeed tells you what is slow. Perfloom tells you which setting to change on your stack.
A free WordPress plugin that reads your theme, page builder, cache plugin and its current settings, then turns PageSpeed findings into steps for the plugins you already run.
The same PageSpeed warning, three different fixes
LiteSpeed Cache can strip unused CSS for you. On this site it is switched off.
- LiteSpeed Cache › Page Optimization › CSS Settings › CSS Minify On
- LiteSpeed Cache › Page Optimization › CSS Settings › Generate UCSS On
- Purge all caches, then check the home page and one Elementor template on mobile.
Generate UCSS uses QUIC.cloud credits. If a section loses its styling, add its CSS file to the UCSS allowlist instead of turning the option off.
WP Rocket and Divi both try to optimise CSS. Pick one, not both.
- WP Rocket › File Optimization › CSS Files › Optimize CSS delivery Remove Unused CSS
- Divi › Theme Options › Performance › Critical CSS Off
- Clear the WP Rocket cache and check the pages built with the Divi Builder.
If you prefer Divi's own Critical CSS, keep it and leave Remove Unused CSS off instead.
Autoptimize can inline the CSS above the fold and defer the rest.
- Settings › Autoptimize › JS, CSS & HTML › Optimize CSS Code On
- Settings › Autoptimize › JS, CSS & HTML › Eliminate render-blocking CSS On
- Appearance › Customize › Performance › Load Google Fonts Locally On in Astra
Check forms and menus after enabling. Deferred CSS can show unstyled content for a moment.
Example recommendations. The plugin writes them for the stack and settings it finds on your site.
Why it is different from another speed report
- It reads the stack from inside WordPress
- Theme, page builder, cache and image plugins, CDN, and the settings that are switched on right now. Nothing is guessed from the outside.
- It works with the plugins you already have
- No new cache plugin to install, nothing to upgrade to, no vendor to favour. Advice only, so nothing changes until you change it.
- Real-user data, private by default
- Core Web Vitals come from Google PageSpeed Insights. Your site's address is never sent to the AI model that writes the advice.
