Is React Native slow, or is performance affected by using Expo?

I have an old Angular app that I packaged within an Android Webview. I've been rewriting it as a React Native app using create-react-native-app, and while it's super-easy to compile it that way, the performance can’t compare to the zippy old Angular app. Even just pressing a custom radio button, causing it to change state and styling, takes a half-second or so compared to near instantaneity with Angular. Is React Native this slow, or is it Expo? Before ejecting and finding out myself, thought I'd see if anyone knows.

I've seen this, and get the approach of creating a webview to display the heatmap in but you still need to link heatmap.min.js to xcode bundle
