What is Time to First Byte (TTFB) - The Concepts of Web Performance

Discover why Time to First Byte (TTFB) is crucial for website speed in this essential Concepts of Web Performance tutorial with Todd Gardner from Request Metrics. Perfect for junior web developers learning performance optimization, this concise guide explains exactly what TTFB measures—the critical waiting period between a user's initial request and your server's first response. Learn how TTFB encompasses redirects, DNS lookups, SSL negotiations, server processing time, and geographical distance, making it the first blocking step in your page's loading sequence. Master the Performance Observer API to accurately track this technical metric, understand why a slow TTFB guarantees poor user experience (that blank white screen users hate!), and discover why Google prioritizes this metric in their performance evaluations. By the end of this video, you'll know exactly how to interpret TTFB data to identify server-side bottlenecks and deliver faster initial response times for your web applications. 🎥 Watch the Concepts of Web Performance videos:    • Concepts of Web Performance   🧑‍🏫 Check out my full training on @FrontendMasters : https://frontendmasters.com/courses/w... 🔥 Start monitoring your website performance with Request Metrics for FREE: https://requestmetrics.com/ #webperformance #webdevelopment #coding #programming
