Consider code splitting or tree shaking to reduce unused code.
This bundle has high unused code — code-split or tree-shake to ship only what executes.

- Convert to woff2 for ~30% smaller file size
Optimization checklist
- Preload critical fonts (priority=high)
- Use woff2 format for all fonts
- Set font-display to swap, optional, or fallback
- Subset large fonts (≤100 KB each)
Fixing the unchecked items could save ~10 KB and ~20 ms

Fonts are always fetched as crossorigin=anonymous; a preload without the attribute creates a different cache key, so the browser refetches when the actual font request happens. Sample: https://sureflo.in/wp-content/themes/Avada/includes/lib/assets/fonts/icomoon/awb-icons.woff, //sureflo.in/wp-content/themes/Avada/includes/lib/assets/fonts/fontawesome/webfonts/fa-brands-400.woff2, //sureflo.in/wp-content/themes/Avada/includes/lib/assets/fonts/fontawesome/webfonts/fa-regular-400.woff2 (+3 more). Add `crossorigin` (or `crossorigin="anonymous"`) to each preload.
Performance issues directly impact user engagement and conversion rates.
