[Paraview] Slowness : paraview 3.10.0 & ProgrammableFilter

[Aashish Chaudhary]

Hi Aurélien,

I found the bug. Very soon I am pushing my changes to VTK and
hopefully by this evening I can update VTK reference in ParaView.

Thanks again for reporting this.

Best Regards,
Aashish

>> Hi all,
>>
>> I perform some calculations in Paraview, through a ProgrammableFilter in which I use several vtk.vtkArrayCalculator objects that I connect between each other with GetOutputPort and GetInputConnection.
>>
>> In the 3.8.1 release of Paraview, such a calculation on a grid with 1.5e6 points need roughly 3 or 4 seconds.
>> In the 3.10.0, using the same tool (an external module, writen in python, that I import into the programmable filter), it takes 6 or 7 times longer.
>>
>> Is there some explanation ?
