The Frontend Performance Paradox: Static vs Dynamic
For years, web architecture forced developers into a tradeoff: deploy static sites for sub-20ms TTFB, or build dynamic server-rendered pages with personalized states that suffered from sluggish response times.
Partial Prerendering (PPR) in Next.js 15 resolves this dichotomy by combining static build-time shells with streaming dynamic Server Components via React 19 Suspense.
Structuring Suspense Boundaries for Optimal First Contentful Paint
// app/dashboard/page.tsx
import { Suspense } from 'react';
import { UserProfileHeader } from '@/components/dashboard/header';
import { RealTimeMetricsStream } from '@/components/dashboard/metrics-stream';
import { SkeletonMetrics } from '@/components/ui/skeletons';
export const experimental_ppr = true;
export default function DashboardPage() {
return (
}>
);
}
| Metric | Standard SSR | Client-Side SPA | Next.js 15 PPR |
|---|---|---|---|
| TTFB (Time to First Byte) | 340ms | 35ms (Static bundle) | 28ms |
| FCP (First Contentful Paint) | 620ms | 890ms | 140ms |
