We are investigating app hangs for our app, and we have added a decent number sentry breadcrumbs for debugging. Do these have significant perf tradeoffs for react-native?

Found this post: https://docs.sentry.io/platforms/react-native/overhead/#breadcrumbs Which seems to answer our question.

Yes we have those enabled and those are firing, but it's hard for us to tell the root cause of those. Are they generally due to console logging?

Logs might also be useful but they are still in beta (available in 7.0.0-RC-1).
