With this middleware you can measure timings on performance tab in the browser's devTools

reducer.ts

const userTiming = () => (next) => (action) => {
  if (performance.mark === undefined) return next(action);
  performance.mark(`${action.type}_start`);
  const result = next(action);
  performance.mark(`${action.type}_end`);
  performance.measure(
    `${action.type}`,
    `${action.type}_start`,
    `${action.type}_end`,
  );
  return result;
}

const store = configureStore({
  reducer: rootReducer,
  devTools: true,
  middleware: (getDefaultMiddleware) => [...getDefaultMiddleware(), userTiming]
});
