[0.82.1] Translation: "The actual performance test results of the TurboModule bridge do not meet expectations

[rexydimen]

Why is there no performance advantage when testing the synchronous bridge of TurboModule in version 0.82.1 compared to the old NativeModules synchronous bridge? Is the testing methodology flawed?
The testing methodology involves clicking a button on the same device after a cold start, then invoking a for-loop to call the TurboModule and NativeModules bridges 1000 times each, measuring total execution time. The results show that TurboModule's performance is inconsistent (fluctuating within a similar range), with some cases even exhibiting degradation.

Our current hypothesis is that the React Native core library's requireModule does not invoke the __turboModuleProxy branch, instead routing all calls to the NativeModules branch. Is this behavior expected?

The code is as follows:
`/**

import { NewAppScreen } from '@react-native/new-app-screen';
import { StatusBar, Button, StyleSheet, useColorScheme, View, NativeModules } from 'react-native';
import {
SafeAreaProvider,
useSafeAreaInsets,
} from 'react-native-safe-area-context';
import UnifiedBridge from './js/NativeUnifiedBridge';
const { OldBridge } = NativeModules;

function App() {
const isDarkMode = useColorScheme() === 'dark';

return (

<StatusBar barStyle={isDarkMode ? 'light-content' : 'dark-content'} />

<Button
onPress={() => {
// TODO 新桥调用测试
const startTime1 = performance.now();
var ret1 = UnifiedBridge.invokeNativeMethodSync(JSON.stringify({ key: Math.random().toString() }));
const endTime1 = performance.now();
console.log('invokeNativeMethodSync took ' + (endTime1 - startTime1) + ' ms ret:' + ret1);
}}

/>

  <View style={{ height: 50 }} />

  <Button
    onPress={() => {
      // TODO 旧桥调用测试
      const startTime = performance.now();
      var ret = OldBridge.syncMethod(JSON.stringify({ key: Math.random().toString() }));
      const endTime = performance.now();
      console.log('OldBridge.syncMethod took ' + (endTime - startTime) + ' ms ret:' + ret);
    }}
    title="旧桥调用"
    color="#272727ff"
    accessibilityLabel="Learn more about this purple button"
  />
  <View style={{ height: 50 }} />
</SafeAreaProvider>

);
}

function AppContent() {
const safeAreaInsets = useSafeAreaInsets();
// callNativeMethod();
return (



);
}

const styles = StyleSheet.create({
container: {
flex: 1,

});

export default App;`
