Next.js 15 vs Astro 4: Benchmark Optimization Guide Choosing between Next.js 15 and Astro 4 for performance-critical projects requires a deep dive into how each framework handles benchmark optimization. This guide breaks down core differences, new optimization features, and real-world benchmark takeaways. What’s New in Next.js 15 for Benchmark Optimization Next.js 15, released in late 2024, prioritizes build and runtime speed improvements. Key updates include: Stable Turbopack : The Rust-based bundler is now production-ready, cutting build times by up to 40% compared to Webpack in internal benchmarks, with faster HMR (Hot Module Replacement) for development workflows. App Router Static Optimization : Enhanced static site generation (SSG) for App Router routes, with automatic static optimization for pages that don’t use dynamic server functions, reducing TTFB (Time to First Byte) for static pages by 15% on average.…
