[vtkusers] Performance comparison between VTk7.0.0 and VTK8.0.1

[Marcelo Duarte Trevisani]

Do you already have a benchmark code to test the differences of performance
between this two versions?

Because I'm thinking to migrate a software to vtk8 + vtkm + opengl2 + tbb
or openmp, but I have to show to my colleagues the advantages regarding the
performance of this new version compiled with these flags, to see if will
be prioritize or not.

I will try to do what you said as well. Thanks.
