TTFB (Time To First Byte) saw the largest improvement at 35% faster.
This makes sense: Nostra operates at the edge layer, meaning it reduces the distance and processing time between a shopper’s request and the first byte returned.
Once that first byte arrives faster, the rest of the page rendering begins instantly, creating downstream improvements in metrics like FCP and LCP.
However, as rendering shifts into the browser, improvements naturally taper since client-side execution is outside infrastructure control.
In other words:
We can make the store load faster.
But we can’t stop someone from opening 37 Chrome tabs while shopping for underwear.
Server response time dropped from 889ms to 575ms — pages start loading the instant a shopper clicks, not a second later.
First Contentful Paint improved from 1,736ms to 1,446ms — customers see product content before friction ever sets in.
No lab metrics here. Results measured across 25.9 million real production sessions with a controlled traffic split — statistically bulletproof.
Edge delivery accelerated the entire experience from first byte to checkout — matching the seamless, no-friction brand promise Tommy John is built on.
300+ enterprise and high-growth brands rely on Nostra to deliver instant site speed, stronger SEO performance, deeper personalization, and clean, actionable marketing data.
