With Fast Edge Cache™

Based on average customer data from production sites. Individual results may vary depending on origin server configuration, content type, and visitor location.

Time to First Byte (TTFB)

Server Response Time

What it measures

TTFB measures the time from when a visitor requests your page to when the first byte of data arrives at their browser. It reflects your server's processing speed and network latency.

Why it matters

Google uses TTFB as a ranking signal. A slow TTFB (over 600ms) triggers the 'Reduce initial server response time' warning in PageSpeed Insights and can drop your performance score by 10-20 points.

How Fast Edge Cache™ helps

  • Edge caching serves responses from 6 global locations
  • 98% cache hit rate eliminates origin server round-trips
  • HTTP/2 and HTTP/3 reduce connection overhead
  • Smart cache warming keeps popular content ready

Largest Contentful Paint (LCP)

Visual Loading Speed

What it measures

LCP measures when the largest visible element (usually a hero image or heading) finishes rendering. It's the primary indicator of perceived loading speed.

Why it matters

LCP is the #1 reason for poor PageSpeed scores. Google requires LCP under 2.5s for a 'Good' rating. Every 100ms delay reduces conversions by up to 7%.

How Fast Edge Cache™ helps

  • Automatic WebP conversion reduces image size by 25-35%
  • Hero images served from nearest edge location
  • Lazy loading for below-fold images
  • Responsive image delivery based on device

First Contentful Paint (FCP)

Initial Render Speed

What it measures

FCP measures when the browser renders the first piece of content from the DOM — text, images, or canvas elements. It tells users 'something is happening.'

Why it matters

FCP directly impacts bounce rate. Users expect content within 1 second. Sites with FCP over 3s see bounce rates increase by 90% compared to sub-1-second sites.

How Fast Edge Cache™ helps

  • HTML cached and served from edge
  • Brotli compression reduces HTML size by 20-30%
  • Critical CSS delivered inline
  • Render-blocking resources minimized
