How to understand how much RAM a method eats?

Question

Google Chrome

There is a fairly massive method that processes data arrays.
On the server, it eats a lot of RAM. I need to find the reason exactly where he eats it.
How to find this location using chrome://inspect.
Made 3 snapshots:
This is at the place of a certain breakpoint in a certain iteration

. This is in a certain period, the initial one.

This is for the entire period of the method.

But I don’t understand what they show. How to find what I need?

Well, in general, google how to find memory leaks and work with heap snapshots in a node. There is no universal answer, but there are methods that can help you. Heap diff helps if you know the moment when the memory is occupied and you can make and compare two snapshots before and after, find what the memory is occupied with and try to find the context with which this data is associated and from the context you may find a method.
