Hi @reactjs developers.
• How do you profile your apps?
• What techniques do you use to determine which of your components might be slow and need refactoring?
• If you could have one new profiling/debugging feature to help with this, what would it be?

I was looking into this today. This looks like a useful tool to catch performance regressions: https://github.com/speedracer/speedracer … Otherwise I use the standalone DevTools, why-did-you-update, and beautiful-react-redux/checks.

The difficult problems are: (1) Getting reconciliation and FPS information out in an automated fashion. Working out which components are too heavy, etc. (2) Detecting when shallow equality checks are failing unnecessarily and why this is happening.
