My results: Preact 2.7.3 took 864920; React 0.14.6 took 435580

There were some benchmarks where Preact was faster, but overall half React's speed.

Preact is using implicit dom recycling, so it heavily breaks use cases like "tree/[*]/render". Just hold mouse over its time and it will display "max" time, it will be much closer to reality.

All other libraries either don't have any form of recycling dom nodes, or it is disabled for this benchmark.
