The number of properties per node roughly corresponds to the number of members of the class the node is representing and should be fairly low. Use std::vector::reserve to prevent reallocation on insert for most node types, there are exceptions like Region(~40 properties). This seems worth it as part(maybe 1/10th of the total time) of saving a Session is a combination of what occurs in "Create" and "Write" in this test.
