Next.js logoISR Performance Benchmark

Next.js ISR on Cloudflare via OpenNext

This application benchmarks Incremental Static Regeneration (ISR) performance for Next.js applications deployed to Cloudflare Workers using OpenNext.

⚡ OpenNext Configuration

  • Incremental Cache: Workers KV (ultra-fast global distribution)
  • Tag Cache: Sharded Durable Objects (high-load on-demand revalidation)
  • Queue: Durable Objects (reliable ISR processing)
  • Cache Interception: Enabled (reduced cold starts)
  • Auto Cache Purge: Direct mode (immediate invalidation)

🧪 Demo Route: /demo/[slug]

Revalidation: Every 10 seconds
Pre-fetched Routes:
/demo/1/demo/2/demo/3/demo/foo/demo/bar/demo/baz
Dynamic Routes: Generated on first request (try /demo/test)

🚀 Test ISR Performance

Visit the demo routes to see ISR in action. Each page shows timestamps, random values, and access counts that update every 10 seconds via ISR.

Pre-generated Routes (Built at Deploy)

/demo/1/demo/2/demo/3/demo/foo/demo/bar/demo/baz

Dynamic Routes (Generated on First Request)

/demo/test/demo/hello/demo/world/demo/performance

📊 What to Observe:

  • • First load: Pre-generated routes should load instantly
  • • Dynamic routes: May have slight delay on first request (cache miss)
  • • Subsequent visits: All routes should be cached and load quickly
  • • Revalidation: Data updates every 10 seconds while maintaining cache performance
