More verbose output from yarn start

[oriooctopus]

When running yarn start, there is no output between "Starting development server" and "Compiled successfully!". In the codebase of my large company, this means there is no output for over a minute. I want to debug our slow setup so I want to see what's going on in that minute. Is there any way to set a "verbose" mode that outputs what's going on during that time?

I've included a video of this from a fresh create-react-app for reference:

npm build --verbose
yarn --versbose start

this might give out some info

Does not work - we too need to get verbose output here.
