React-native – Slow performance of React Native Android without Chrome debugging

I am experiencing performance issues on React Native Android. I am using Redux.

The problem is that when I turn on chrome debugging, my app Works fine (fast). When I close the remote debugger, the performance becomes very slow. I just want to know if this is normal. I have read other threads saying that in debug mode, the performance is performed on chrome itself, so It’s faster. Is the performance gap so big?

Thank you.

I encountered the same performance problem, which is very Bad experience. You need to delete any console.log(‘show_me_some_data’) and then you will get better performance. I think that every time you encounter console.log, react-native tries to find the remote debugger. Reaction takes time , This is the reason for the performance degradation. This is just my suggestion, but it worked for me.

Hope this will help someone.
