Which routing package give me best performance in route change?


I am developing mobile app using meteor. And i am suffering from page transition delay in mobile. Currently i am using iron router with animation css so i can get native app kind look. But page rendering delay is behaving not good my app. I dont know that iron router is the reason for this delay or not. So i want to know that anyone know that flowrouter will solve my problem? Because conversion of iron router to flow router will affect my whole system.
