In my opinion, with current architecture NativeScript won't be that performant.

They have very thin layer of native runtime, but majority of the UI core modules are kept in JavaScript/TypeScript. UI rendering will require too much of to-and-fro between V8 engine (or JavascriptCore) and NativeScript runtime.

Ideally they should have pushed much of the UI core modules in the runtime itself, along with JavaScript modules that have fewer calls to layout a view. Their current methodology would require too many proxy calls just to set layout properties.
