Measures time-to-first-byte in seconds, for single or multiple URLs. Can calculate fastest, slowest & median TTFB values, and optionally log all response headers. Uses curl and the calculation `%{time_starttransfer} - %{time_appconnect}` which doesn't include any connection overhead, to better approximate devtool’s TTFB figure.
A the moment we show values like
