TTFB doesn't mean what you think it means
Time-To-First-Byte (TTFB) is a popular performance metric, yet there are many problems and nuances with it. It has a variety of divergent definitions and tools often measure it in (slightly) different ways. In this talk, we'll explore how and why this can be a problem in practice, especially when comparing TTFB numbers from different sources (such as CrUX, RUM and synthetic measurements). You'll walk away with a better idea of how to deal with TTFB discrepancies, as they're sure to show up!
