Performance issue with collecting vtkPVArrayInformation
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
vtkPVArrayInformation::CopyFromObject() has become very slow with large number of points/cells.
Open motorbike.vtm and show it as surface. If you look at the timer log, XMLMultiBlockDataReader::GatherInformation, and vtkSMRepresentationProxy::GetRepresentedDataInformation take the longest time and both being bottled necked in the vtkPVArrayInformation::CopyFromObject() code.
The problem was also noticed with other datasets.
