Performance Kit
Core Web Vitals in the green
Smart caching, image optimization and asset tuning that push your LCP, CLS and INP into the green — measurable in your dashboard.
Performance Kit attacks the three things that make Shopware shops slow: cold caches, oversized images and unoptimized assets. Its smart cache warmer learns your traffic patterns and keeps the right pages hot, the image pipeline delivers AVIF/WebP in exactly the right sizes, and asset tuning defers, bundles and lazy-loads what browsers don't need immediately. Every optimization is measured — you see LCP, CLS and INP per device class in the plugin dashboard, before and after.

Will it conflict with my CDN?
No — it plays well with Cloudflare, Fastly and Akamai, and its headers make CDN caching more effective, not less.
How much faster will my shop be?
Typical results: LCP down 30–55% and INP in the green band. Your exact numbers show in the vitals dashboard from day one.
Does it work with heavily themed shops?
Yes — asset tuning detects your theme's build and adapts. Safe mode lets you roll out changes gradually.
