Common Next.js Performance Issues
Large JavaScript bundles
Next.js sites often include heavy JavaScript that blocks rendering. Consider code splitting and lazy loading.
Unoptimized images
Images are typically the largest assets. Use modern formats (WebP/AVIF) and proper lazy loading.
Render-blocking resources
CSS and JavaScript files can delay page rendering. Defer or async load non-critical resources.
Third-party scripts
Analytics, ads, and social widgets add overhead. Load them after your main content.
