I'm thinking #7240 (comment) and further reports. But not sure if that was related or not.
Less events is better. onSetDisplayName, onSetOwner, and onSetText only existed because we didn't initially track elements.
| onSetText(id, text) { | ||
| update(id, item => item.text = text); | ||
| onInstantiateComponent(id, element) { | ||
| create(id, element); |

This is now the only place where we create entries. All others have been changed to vanilla get.

This is excellent. I love the create/get separation. |

Removing some additional DEV regressions.
This does two things:
onSetOwner,onSetDisplayNameandonSetTextwith one eventWe can do this now easily because we track elements.
This gives me 1.5x improvements in both mounting and unmounting time in DEV.
I tested with https://github.com/gaearon/js-framework-benchmark/tree/master/react-v15.3.0.
