Perf isn’t just about how fast your framework runs.
Perf is also about:
- how fast you can set up a dev environment for it
- how fast you can train people to use it
- how fast they become productive in it
Every app needs one primary metric — Friction. This is a function of how easy it is for users of the app to do what they came to do and how long it takes them to do it. Every other metric flows from that, even revenue earned — because if your users encounter too much friction, you’re not gonna get any revenue.
