Render the page faster. Enhance your site's load page for Core Web Vital.
This plugin is no longer maintained and will be closed on WordPress.org.
When Render Faster was first released (2021), it provided features that were missing from WordPress core. Since then, WordPress has absorbed most of those optimizations natively, which means this plugin is no longer necessary on modern WordPress sites (6.3+).
If you are currently using Render Faster, please deactivate and remove it, and use the replacements described below.
| Feature of Render Faster | Replacement | Available since |
|---|---|---|
loading="lazy" on <img> |
WordPress core (automatic) | WP 5.5 |
loading="lazy" on <iframe> |
WordPress core (automatic) | WP 5.7 |
fetchpriority="high" / eager loading for the LCP image |
WordPress core (automatic) | WP 6.3 |
defer / async on scripts |
Script Loading Strategies API — pass strategy to wp_enqueue_script() / wp_register_script() |
WP 6.3 |
| Loading only the block styles used on the page | should_load_separate_core_block_assets filter, or wp_enqueue_block_style() |
WP 5.8 |
Removing jquery-migrate |
A small custom snippet, or a dedicated plugin such as Disable jQuery Migrate | — |
Preloading stylesheets (rel="preload") and the loadCSS polyfill |
Not recommended on modern browsers. Consider Critical CSS tooling or a full-featured performance plugin (WP Rocket, NitroPack, FlyingPress, LiteSpeed Cache, Jetpack Boost, etc.) | — |
| Lazy loading Twitter / Instagram embed helper scripts | Handle inside your theme, or use a full-featured performance plugin listed above | — |
This plugin optimize page rendering of WordPress theme.
- Add
loading="lazy"orloading="eager"with your images. - Add
deferorasyncattributes to your scripts. - Add
rel="preload"to your stylesheets. Polyfill for old browsers is also available. - Remove default script helper of embeds(twitter, instagram) and load one after user interaction.
All of above are selectable and you can customize with white list.
If you wish header logo(.custom-logo) and main post thumbnail(.post-feature-image) should be load faster because they are in first view.
Just put custom-logo,post-feature-image at High Priority section in your setting screen.
Defering JavaScripts sometimes breaks your site. For example, if a script requires just in time operation with inline script tag, it will fail.
<script id="some-script-js" src="somescript.js" defer></script>
<script>
new SomeScript();
</script>
To avoid this, Add some-script handle name in Deny Defer section in your setting screen.
Generally speaking, many JavaScripts loaded in your WordPress are issued by WordPress Core, plugins, themes, your custom code, and so on.
To optimize JavaScript loading, try and error approaches works fine.
rel="preload" attributes makes your stylesheets loaded asynchrounsely, but FOUC(Flush of Unstyled Content) happens.
To avoid this, include critical CSS to Deny List in your setting screen. Critical CSS are generally your theme's main stylesheet.
Click install and activate it.
