[Paraview] CellDataToPointData much slower in 5.0?

[Ken Martin]

Pulled this off list since I have some ignorant questions to ask :-)

So I loaded the data and it seems to render fine (100 fps).  I did not have
the state file so I'm not sure what pipeline etc is being used.  When I hit
the animation button it plugs along at one frame a second or so. I have no
clue if that is what is expected or not. It appears that the rendering data
is being rebuilt every frame. Again I just don't know enough about PV to
know if that is expected or not. I would think PV would cache the timesteps
if the size is modest but maybe not. I will build PV and run it in the
profiler but it may be tomorrow before the build wraps up.

If you have a modest VTK example then I could probably answer your question
easily.But PV is a much more complex beast and I do not know the internals
well enough to guess.

Thanks
Ken
