## Common issues

**Low cache hit rate:** Check your [cache configuration](/cdn/smart-cache) and ensure cacheable content has appropriate headers.

**Origin slow to respond:** Consider enabling [Origin Shield](/cdn/performance/origin-shield) to reduce origin load, or check your origin server performance.

**Large assets:** Enable [Bunny Optimizer](/optimizer) for automatic image optimization, or compress assets before uploading.

**Too many requests:** Combine CSS/JS files, use sprites for icons, and implement lazy loading for images.
