How does the memory usage of a List<T> compare to a LinkedList<T>?

• List<T> uses a contiguous array internally, so memory is compact and

cache-friendly.

• LinkedList<T> stores elements in nodes with extra pointers (Next and

Previous), leading to more memory overhead.

• Therefore, List<T> generally has lower memory usage and better cache

performance than LinkedList<T>, especially for large collections.
