React Studio file can really big if you are tackling a big project. My project went up to 288 megabytes 4 days ago. At this point, your day can become very unproductive, considering the 3 to 5 minutes in my case do compile or just trying to open a component or screen.

Actually, there was a little found and delete, but the results are remarkable. From 276.9 to 76.4
What I learn:
1.As a good practice try to keep as minimal as you can the number of components used in your project.
