Inside of a
List<T>, there is a statically sized collection that holds your items. Once you reach the capacity of that collection, theList<T>re-sizing it which is a performance hit (may or may not be significant to you).By setting the initial capacity, you are avoiding having to perform those re-sizing operations.
