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. Last modified on June 26, 2026
