描述

Hi , i have made a simple test with react motion.

As soon as i add the @Radium decorator it slows down quite a lot. The difference isn't really noticable on desktop, but on a mobile device it is a big difference.

please see the tests here : https://github.com/Aaike/react-motion-radium-test There are links to 2 tests. The only difference in the 2 demos is the addition of the @Radium decorator.

Please look at those tests with a chrome browser on a mobile device.

Do you have any suggestions to avoid this drop in performance ?

研究方向
The issue reports performance slowdown with Radium decorator on mobile. The reporter provided a test repo (https://github.com/Aaike/react motion radium test). Investigate using React Profiler to identify costly renders. Look at Radium's source code for any unnecessary re renders or heavy computations. Consider implementing shouldComponentUpdate or using PureComponent to mitigate the issue.
