Common issues

Low cache hit rate: Check your cache configuration and ensure cacheable content has appropriate headers. Origin slow to respond: Consider enabling Origin Shield to reduce origin load, or check your origin server performance. Large assets: Enable Bunny 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.
