10 Next.js Performance Mistakes That Slow Down Production Apps

Angular applications often experience performance degradation as they grow, where complex screens and shared state cause delayed interactions and laggy search fields. Similarly, Next.js apps may feel fast during development but slow down in production due to larger datasets, network latency, and third-party scripts. While Next.js offers Server Components and image optimization, these tools only improve speed if used correctly, preventing the performance drops seen when transitioning from local environments to real-world usage.
