How Layer0 improves
website speed
Layer0 enables sub-500ms page loads for large eCommerce websites with 1000s of SKUs, A/B tests, dynamic pricing, real-time inventory lookups, and promotions.
What’s inside?
By combining server-side rendering with advanced predictive prefetching and pre-caching at the edge, Layer0 achieves 399ms average page loads, measured by Largest Contentful Paint. Dynamic data is cached at least 95% of the time, so your database is protected from the extra requests created by prefetching. Layer0’s CDN-as-JavaScript service worker intelligently fetches your dynamic pages before your visitor taps on a link for an instant load every time.
Delivering peak performance from homepage to checkout.
Our goal is to deliver home page LCPs in less than 1.5 seconds, PLP to PDP navigation in 0.5 seconds and Lighthouse Scores in the 90th percentile. To do so, Layer0 optimizes the following metrics:
- First Contentful Paint (FCP)
- Speed Index (SI)
- Largest Contentful Paint (LCP)
- First Input Delay (FID)
- Cumulative Layout Shift (CLS)
- Time to First Byte (TTFB)
- Total Blocking Time (TBT)
- Time to Live (TTL)
