Optimize IfcOpenShell performance by utilizing the geometry iterator for batch mesh generation and applying selective data loading. These memory management strategies prevent system crashes when processing large IFC models exceeding 100MB.

Speed up geometry processing in IfcOpenShell by replacing `create_shape()` with `ifcopenshell.geom.iterator` and enabling multiprocessing. This batch API approach significantly accelerates mesh generation for large IFC models.

Extracting wall geometry takes hours because standard `create_shape()` calls lack batch processing and caching. Switching to `ifcopenshell.geom.iterator` with proper settings reduces processing time from hours to minutes.

Yes, you can use IfcOpenShell iterators for batch API calls and caching. The `ifcopenshell.geom.iterator` supports multiprocessing and selective data loading to efficiently handle massive IFC models while reducing memory footprint.

Profile IfcOpenShell operations by analyzing iterator usage, batch API calls, and caching mechanisms. This identifies bottlenecks in geometry processing, allowing you to apply efficient data retrieval strategies that reduce processing time and memory footprint.
