Troubleshooting: Performance issues / slow cart open
Diagnose slow cart drawer rendering and fix the most common causes.
Check Web Vitals first
Open Analytics → Web Vitals. If LCP is high (>2.5s) or CLS is high (>0.1), the data tells you what to fix.
Common fixes
Reduce in-cart widget count
Every widget — recommendations, trust badges, announcement bar — adds rendering cost. Trim to essentials.
Disable auto-open animation
If auto-open animation is causing layout shift on slow devices, disable it.
Check hero images
Confirm your theme isn't loading 5MB hero images via the recommendation widget. Compress images or use WebP.
Reduce custom HTML / CSS
Heavy custom injections can slow first render. Strip to essentials.
If the entire storefront is slow
The cart drawer can amplify existing theme performance issues but rarely causes them alone. Run PageSpeed Insights on a non-cart page (homepage, PDP) to confirm — if those are also slow, the issue is theme-wide, not Oxify.
