How to Optimize Firebase Realtime Database Performance in .NET MAUI

Using .NET MAUI with Firebase Realtime Database, issues have been encountered with slow loading times for user data in the app. When new data is added to Firebase, there is also a significant delay in reflecting these changes. What strategies can be implemented to reduce this delay and improve app performance?
This is my View Model class

public ProfilePageViewModel(INavigation navigation, FirebaseManager _firebaseManager)
{
    firebaseClient = new FirebaseClient(DatabaseUrl);
    Navigation = navigation;
    firebaseManager = _firebaseManager;
    PaymentMethods = new ObservableCollection<PaymentModel>();
    LoadUserData();
}

private async void LoadUserData()
{
    await FetchUserDataAsync();
}

public async Task FetchUserDataAsync()
{
    UserId = Preferences.Get("LocalId", string.Empty);
    IsLoading = true;

    var observable = firebaseClient
    .Child("UserData")
    .Child(UserId)
    .AsObservable<UserDataModel>();

    observable.Subscribe(user =>
    {
        UserData = user.Object;
        FullName = UserData.FirstName + " " + UserData.LastName;
    }, error =>
    {
        Console.WriteLine("Error while fetching user data: " + error.Message);
    });
    IsLoading = false;
}
}
```This is my model class 


```powershell
  public class UserDataModel
  {
      public string Id { get; set; }
      public string Email { get; set; }
      public string FirstName { get; set; }
      public string LastName { get; set; }
      public string MobileNumber { get; set; }
      public ObservableCollection<PaymentModel> PaymentMethod { get; set; } = new ObservableCollection<PaymentModel>();
      public string Image { get; set; }
      public string Address { get; set; }
      public double Latitude { get; set; }
      public double Longitude { get; set; }
  }
  public partial class PaymentModel : ObservableObject
  {
      public string PaymentEmail { get; set; }
      public string CardNumber { get; set; }
      public string CVV { get; set; }
      public string ExpiryDate { get; set; }
      public string PaymentMethodName { get; set; }
}
