Maya API 2.0 DAG traversal performance during complex hierarchy manipulation

Production pipelines often require high-frequency traversal of the Directed Acyclic Graph (DAG) to perform scene transformations. While the maya.api.OpenMaya (API 2.0) module is documented to provide better performance than maya.cmds or PyMEL by reducing Python-to-C++ conversion overhead, the optimal approach for accessing node data during deep hierarchy iterations remains unclear.

The primary goal is to minimize memory overhead and execution time when manipulating thousands of DAG nodes. There is a design trade-off between using the higher-level maya.cmds for stability and the lower-level API 2.0 for direct memory access to nodes.

• Does API 2.0 provide a measurable performance advantage over maya.cmds specifically for recursive DAG traversal in versions 2024 and later?
• What are the memory implications of maintaining long-lived API 2.0 object references during large-scale scene manipulations?
