Stop worrying about Time To First Byte (TTFB)

What this post added

This post critically analyzes the metric of Time To First Byte (TTFB), demonstrating through experiments that it can be a misleading indicator of actual page load speed, particularly when optimizations like gzip compression are applied. It highlights that TTFB can be negatively correlated with download time, and that Cloudflare's focus is on optimizing the real end-user page visibility time, not just TTFB. The post also mentions the development of tools to monitor end-user experience.
