Slow page response

How to fix it

Profile the page, fix backend hot spots, enable caching, and trim render-blocking resources.

Sibling checks in this category

• Oversized HTML - The HTML payload is unusually large, slowing parsing and hurting Core Web Vitals.
• No HTTP compression - The response is not gzip / br compressed, wasting bandwidth and slowing time-to-first-byte for clients.
• Slow time-to-first-byte - TTFB is high, indicating server or origin latency. This drags every other metric.
