Common Next.js Performance Issues

1

Large JavaScript bundles

Next.js sites often include heavy JavaScript that blocks rendering. Consider code splitting and lazy loading.

2

Unoptimized images

Images are typically the largest assets. Use modern formats (WebP/AVIF) and proper lazy loading.

3

Render-blocking resources

CSS and JavaScript files can delay page rendering. Defer or async load non-critical resources.

4

Third-party scripts

Analytics, ads, and social widgets add overhead. Load them after your main content.
