🚀 3. Page Optimization

Most speed improvements happen here — minify, combine, and load CSS/JS efficiently.

CSS Settings

Minify and Combine CSS for smaller page size. Personally I don’t combine css because it was breaking something on my website. Be sure to Open Toolbox and Purge all Cache after toggling this on.
Generate UCSS: Removes unused styles (requires QUIC.cloud). Requires CSS Combine ON.
Load CSS Asynchronously: Prevents blocking page load.

JS Settings

Minify JS and defer load for better performance. Careful — may break scripts. Personally I don’t use this because it caused issues with my website.
Be sure to Open Toolbox and Purge all Cache after toggling this on.

🖼️ 4. Media Settings

Optimize and lazy load images to improve load times.

Enable Lazy Load for images and iframes. If you enable lazy load you will want to enable VPI (Viewport Images) aswell. VPI allows your website to cache and display images known to be in the initial view of the user. This way the rendering doesn’t lag and the image is shown on time to the user.

🌐 5. CDN Settings

Content Delivery Network helps deliver your site faster across the globe.

Enable CDN using quic.cloud, cloudflare, or other static CDN
Enable HTML Rewrites to rewrite asset paths. To do this you must add this code to your .htaccess file.

Litespeed htaccess File Edit — CPanel – File Manager – .htaccess location

Integrate with QUIC.cloud or Cloudflare. Some shared hosts may block their IP Addresses. You will know if you try to enable CDN in quiccloud and you get a 520 error on your website. BE CAREFUL – Once you get this error the only way to remove it and get back into your WordPress Site is to disable it through the QuicCloud dashboard. It will take a couple minutes to fix itself.

📋 6. Database Optimization

Clean up post revisions, transients, and other clutter.

Remove post revisions, drafts, and spam comments.
Optimize tables regularly to keep the database lean.

🔄 7. Crawler Settings (Optional)

Preloads pages into the cache so they’re always fast, but watch server usage.

Enable Crawler if your host supports it. A shared host may not support this to lessen server load. To enable one must edit an apache file on server side. Follow Litespeed Doc
Set conservative intervals to avoid server load issues.

Pro Tip: Test your site with tools like Google PageSpeed Insights, GTmetrix, and WebPageTest after each change.
