Add element in an ArrayList efficiently at a given index in java

I need to insert a element of type Person (my own defined class) in an ArrayList at index i

I know I can use add(int index, E element).

But is there any efficient method to do this as in my list it is taking around 1.5 ms on an average (data collected over 1000 insertion and then average).
