We've got some SectionList and FlatList components in the app that can get pretty long (e.g. our Unit screen lists out every lesson and content-item in there, that's pretty big.)
We use the initialNumToRender prop to help out with rendering long lists like that - dunno if that's one of your performance bits, but it was a big help to us!
