How to optimize the storage of a large number of objects?

Question

.NET

There is a program that deserializes an Xml array into objects of a certain type (Purely for example, the Human type with fields name, age, city, etc.) of type and displays them in a ListView. The bottom line is that without loading even a quarter of the objects that will have to be used in the program, and having a very simple interface, in fact, the ListBox itself and nothing else, it takes 20 MB of RAM. I would like to know what are the ways to make this process less resource-intensive. And the more detailed the better. Thanks
