Hello, Andrei,
Thank you for reaching out and for providing detailed information about your setup and optimization efforts.
We appreciate the time you have taken to analyze your website’s performance and share the results. Based on your description, please find below our recommendations and clarifications:
1. Reducing the CSS file size
The main CSS file is generated dynamically based on the active theme options and modules. To reduce its size, we recommend disabling any unused modules in XStore > Theme Options > Speed Optimization. You can also enable the “Remove Unused CSS” option in LiteSpeed, as you already have, and ensure that the “Combine CSS”* option is disabled to allow asynchronous loading.
2. Recommended performance settings for XStore + Elementor + LiteSpeed Cache
– Keep CSS/JS Minify and Load CSS Asynchronously enabled.
– Disable Combine CSS/JS in LiteSpeed.
– Enable Lazy Load for images and iframes.
– Exclude critical theme scripts (like jQuery) from delay if they are required for initial rendering.
– Use the XStore > Theme Options > Speed Optimization section to disable unnecessary scripts and libraries.
3. Loading theme fonts asynchronously
If you are not using custom fonts, you can disable unused font files in XStore > Theme Options > Typography by selecting system fonts only.
4. Modules affecting LCP
Dynamic elements such as the Product Carousel, Sales Booster, and Sticky Cart can influence LCP due to additional scripts and rendering time. You may test disabling these modules temporarily to measure their impact using PageSpeed Insights.
5. Modules to disable for performance
We recommend disabling any modules that are not essential for your website’s functionality, such as 360° View, Compare, Popup Builder, or Extra Product Options, if not in use. The fewer active modules, the smaller the CSS and JS footprint.
For further improvement, you can also test your site with GTmetrix or WebPageTest to identify specific scripts or styles that delay rendering.
If you would like, please provide temporary admin access (via a secure private message) so our technical team can review your configuration and suggest more precise adjustments.
Thank you for your cooperation and for choosing XStore.
Best Regards,
8Theme’s Team
