So here is what I have found so far. The problem is the usage of Map/HashMap that the Order and Item uses to store its children.
Order has many Items
Item has many Attributes.
Interestingly I am not even using Attributes, just the presence of that causes the test to take about 30-40% more memory.
Here is what I have observed for a test that I am running
test, Heap, PermGen, CPU, Classes loaded
With Maps for both, 468M , 112M, 8%, 11,000
No Attribute Map, 285M, 64M, 5%, 7,000
No Item and Attribute Map, 74M, 16M, 1%, 3,300
I am going to continue to try other things, but looks like I have my culprit. The question is if this is a bug or expected??
