React Conf talk from 2015](https://www.youtube.com/watch?v=z5e7kWSHWTg) interesting demos were presented. One of them was also a performance test and comparison with other reactive rendering engines. Blaze was not among them. But I [implemented it](https://github.com/mitar/reactconf-2015-HYPE) and discovered that it sadly performs much slower than React.js.

Thanks for creating a good example of a case where Blaze performance could be better. We definitely need more benchmarks so that we can track improvements in performance over time.\r\n\r\nDo you think there is a way to convert this app to a benchmark that returns numbers about performance? Then it will be much easier to gather actionable data."}}
