Cue server-timing headers Historically, when looking at page speed, we've had the tendency to ignore TTFB when trying to optimize the user experience. Caching the base page/HTML is common, and it should have a positive impact on backend times. The use of server-timing headers by content delivery networks closes a big gap.
