Performance guidelines
- Ideally, every page loads in 200ms. (Why half of the Doherty threshold? Because if it’s 200ms in the US on a high-speed connection and relatively new hardware, it’s going to be slower for anyone not-US, not-high-speed or not-new-hardware, and we want to do our best to stay under the Doherty threshold in those situations.)
- There is no top-level loading number recommendation from UX, because it's a very context-specific decision.
- Worst case scenario is that the connection consistently times out or the volume of data crashes the user’s browser – we consider both of these cases total user experience failure and they should be avoided.
