🔍 Key Findings

Root Cause: Browser connection limit (6-10 per domain) causes 87.7% of images to wait in queue with average 19.7s blocked time.
CDN Performance: Individual images load fast (113ms TTFB, 212ms total). Server: Google-Edge-Cache (Media CDN).
Cache Status: Images are properly cached (X-Cache: hit, Age: 84120s). Caching is working correctly.
HTTP Protocol: Using HTTP/2 (1,058 images) and HTTP/3 (10 images). Single connection serving all images.
Best Solution: Implement lazy loading (loading="lazy") for 97% improvement, or use multiple CDN domains for 65% improvement.
