Hello 8theme Support Team,

We are using XStore (WordPress + WooCommerce + Elementor) and we cannot get acceptable PageSpeed scores, even after following your official speed guide from the documentation (“The Ultimate 2025 Guide to Boosting WordPress Speed with XStore Theme”).

Context:

* We built a fresh staging version using XStore, then rebuilt the layout on top of it (Elementor header + homepage).
* Hosting runs LiteSpeed + LiteSpeed Cache plugin.
* Current Google PageSpeed Insights scores are consistently low:

* Mobile Performance around 20–30 (varies between runs)
* Desktop Performance around 35–40 (varies between runs)
* Accessibility/Best Practices/SEO are OK, but Performance is the blocker.

Main Lighthouse issues we see:

* High Total Blocking Time (2s+)
* High LCP (up to ~8–9s on mobile in some runs)
* CLS spikes (we see ~0.4 on desktop in some runs)

What we need from you:

1. Please review our current XStore theme configuration and advise what XStore modules/features/settings should be disabled or adjusted for maximum performance (especially for Elementor + WooCommerce).
2. If you have a recommended “minimal performance preset” for XStore + Elementor, please share it.
3. If needed, we can provide temporary staging access for you to inspect directly.

Attachments (as requested):

* XStore theme options export (JSON)
* LiteSpeed Cache settings export
* Latest PageSpeed Insights screenshots (mobile + desktop)
* Plugin list + versions (Site Health export)

We tried to do this ourselves, but we are stuck and we need a clear action plan to reach 90+ PageSpeed on both mobile and desktop.

Thank you

Hello, Andrei,

Unfortunately, the use of Elementor places a significant load on the system. We kindly ask you to provide us with access to the admin panel so that we can disable unnecessary elements.

Best regards,
8Theme Team

Hello,

Thank you for your reply.

We understand that Elementor can increase system load. However, before providing admin access, we would appreciate more specific guidance from your side.

Could you please clarify:

Which exact Elementor features or modules should be disabled to improve performance?

Are there specific Elementor experiments or settings that conflict with XStore?

Are there known Elementor scripts that should be excluded from LiteSpeed JS Deferred?

Is there an official recommended Elementor configuration for XStore to achieve optimal Core Web Vitals?

Currently:

We are not using excessive widgets.

Many XStore modules are already disabled (Quick View, Swatches, Compare, Wishlist, Ajax Filters).

JS Deferred breaks animations and filters even with exclusions.

PageSpeed shows heavy execution time from the main XStore JS file.

If Elementor is the main issue, we need clear guidance on:

What to disable inside Elementor → Settings → Advanced / Experiments

Whether to disable Elementor Icons, FontAwesome, Motion Effects, etc.

Whether to enable “Optimized DOM Output” and “Load Icons Inline”

Whether to disable Elementor Swiper (if XStore handles it)

We are trying to optimize properly and would prefer to adjust the configuration ourselves if possible.

Please advise on the recommended Elementor + XStore performance setup.

Thank you.

Best regards

Hello,

Thank you for your response.

I would like to inform you that we have already applied additional Elementor performance optimizations on our side:

In Elementor → Settings → Advanced:

Google Fonts → Disabled

Form Submissions → Disabled

Font Awesome 4 Support → Disabled

Tag Generator → Disabled

Unfiltered File Uploads → Disabled

In Elementor → Settings → Performance:

CSS Print Method → External

Optimized Image Loading → Enabled

Optimized Gutenberg Loading → Enabled

Background Image Lazy Load → Enabled

Optimized DOM Output → Enabled

Improved Asset Loading → Enabled

Optimized Markup → Enabled

We also kept many XStore modules disabled:

Quick View

Swatches

Compare

Wishlist

Ajax Filters

LiteSpeed configuration:

JS Minify → ON

JS Combine → OFF

JS Deferred → OFF (because enabling it breaks animations, filters and interactive functionality even with exclusions like elementor, swiper, etheme)

CSS Minify → ON

CSS Combine → ON

Generate UCSS → ON

UCSS Inline → ON

Despite all of the above, PageSpeed still shows heavy main-thread execution coming from the main XStore JS file.

At this stage, we would really appreciate:

Confirmation whether the XStore main JS file can be safely deferred.

The exact JS exclusion list officially recommended for LiteSpeed.

Whether “Disable jQuery Migrate” and “Disable Theme Swiper JS” are safe in a WooCommerce + Elementor setup.

Whether Brands module loads global scripts on every page.

We have already applied all reasonable Elementor optimizations and would like precise guidance regarding XStore core scripts.

Looking forward to your recommendations.

Best regards

From PageSpeed Insights mobile report, we identified that multiple font weights are creating a long critical request chain:

Loaded fonts:

RethinkSans (Regular, Medium, Bold)

Gabarito (Regular, SemiBold, Bold)

XStore icons

This results in a 3.6s critical path latency on mobile and impacts LCP rendering (the LCP element is a heading).

Could you please confirm:

Which font files are strictly required for default XStore layout?

Is there a way to limit font weights globally from the theme without breaking layout?

Can unused font weights be safely deregistered?

Does XStore preload fonts automatically, or should we manually preload only the primary font?

Are there any recommended typography optimizations specifically for WooCommerce mobile performance?

Our goal:

Reduce critical font chain

Keep layout intact

Improve mobile LCP

Looking forward to your technical guidance

Hello,

After implementing all recommended performance optimizations, we are facing a severe mobile performance issue.

Current situation:

Desktop score: 99
Mobile score: 30

The mobile LCP element is now being detected as the CookieYes banner text instead of the hero section.

However, the main issue appears to be excessive main-thread execution from the XStore core JS file:

Main file:

/js/196da2e….js?ver=6234a

Issues observed in Lighthouse:

• 6,188 ms CPU time
• 3,368 ms Style & Layout
• Significant forced reflows triggered by XStore JS
• Reduce unused JavaScript: 222 KB unused
• Render blocking CSS still 149 KB even with UCSS enabled

We have already:

• Removed custom fonts
• Enabled UCSS
• Disabled CSS Combine
• Enabled CSS Minify
• Enabled JS Minify
• Enabled Font Display Swap
• Optimized images
• Optimized cache

Yet mobile performance collapses due to:

Heavy XStore JS execution

Forced reflows caused by theme scripts

CSS bundle still large even with UCSS

Please clarify:

Is there a recommended minimal JS mode for XStore?

Can main theme JS be split or conditionally loaded?

Is there a way to disable unnecessary modules globally?

Is there an official mobile performance configuration for XStore + LiteSpeed?

We need to achieve stable 90+ mobile performance without breaking functionality.

Thank you.

Could you please provide temporary wp-admin and FTP access? We will check what can be done to help you.
To grant WP-Admin access, please proceed to create a new user account with an administrator role through your WordPress Dashboard. Once the account is established, you may securely transmit the username and password to us via the Private Content section designated for this purpose.

For FTP access, we require the following details: FTP host, FTP username, FTP password, FTP port, and FTP encryption type. If you need assistance in creating these credentials, please reach out to your hosting provider who will guide you through the process.

Hello, Andrei,

In this case, we kindly ask you to send us a screenshot of the WP Rocket cache plugin settings, specifically the scripts and styles that are excluded from caching. We also need to know which theme speed optimization options you have enabled. To do this, please go to the Theme Options → Speed Optimization section and take a screenshot as well.

Additionally, please go to the Elementor settings section, review the widgets in use, and disable any unnecessary ones. You also need to configure CDN and GZIP compression on your server. You can find more information about this in the following articles.

Hello, Andrei,

We have not detected any conflicts between XStore and LiteSpeed.

You did not specify whether you have disabled unnecessary Elementor widgets. You can view them – please check the attached video for reference.

Also, please confirm whether the wishlist is enabled for variable products. Regarding the CDN, we recommend using Cloudflare, as it not only improves performance but also provides protection against bot attacks.
