WordPress Performance Fix, Manual Fix Only

Here are the key performance issues flagged across both platforms

Mobile-Specific Issues
• Slow Initial Server Response Time
Optimize backend performance and hosting configuration to reduce TTFB.
• Render-Blocking Resources
Defer non-critical JS and inline critical CSS to speed up first paint.
• Large Layout Shifts (CLS)
Ensure dimensions are set for images and embeds to prevent visual instability.
• Unoptimized Images
Resize and compress images for mobile and consider using WebP format.
• Heavy JavaScript Execution
Audit and streamline scripts to reduce main thread work.

Desktop-Specific Issues
• Unused JavaScript and CSS
Remove or split unused code to reduce payload size.
• Efficient Cache Policy Missing
Set long cache lifetimes for static assets to improve repeat-load performance.
• Large DOM Size
Simplify the DOM structure to reduce parsing and rendering time.
• Text Compression Not Enabled
Enable gzip or Brotli compression for HTML, CSS, and JS files
Everything must stay in line with WooCommerce
