how much memory is this using?


It depends on how are you doing the variables allocations & stuff. It still can be optimised. Local variables can also help.
Also garbage collector can help a lot. node.heap() only cannot help too much to understand exactly how much memory is used in the running process itself, but didn't have problems with exceeding available memory.
