Significant performance regression in vtkGeometryFilter
In a vtk app, we are using a simple pipeline with vtkGeometryFilter
connected to vtkPolyDataNormals
to extract the surface of an unstructured grid with millions of tets and prisms. We are using the TBB SMPtools backend on linux.
Between July 22 and Sept 23, the time to extract roughly doubled from 10 to 20 seconds for a mesh with 11M tets and 50M prisms.
This is the time frame where the SMPTools backend was made dynamic - was performance checked for vtkGeometryFilter for this change?
