प्रदर्शन मेट्रिक्स की बुनियादें

पहले बाइट का समय (TTFB)

TTFB is the time from request to first byte of response. Includes network latency and server processing. Target: < 600ms. Optimize server response time and use CDN to reduce this metric.

पहली सामग्री पेंट (FCP)

FCP marks when first content (text, image, or background) appears. Target: < 1.8 seconds. Critical for perceived load performance—users want to see something quickly.

इंटरैक्टिव समय (TTI)

TTI is when the page becomes fully interactive. Heavy JavaScript can delay this. Focus on reducing main thread blocking and ensuring responsive interactions after content loads.

मेट्रिक संबंध

Timeline: TTFB → FCP → LCP → TTI. Each metric builds on previous. Understanding this sequence helps identify bottlenecks. A high TTFB affects all downstream metrics.
