Your grid size is quite large i.e. above 3 million grid points, which is generally 
difficult for VTK to handle on a single machine.

Paraview has an intelligent mechanism by which is uses different filters 
(which are more efficient and are panented ones) when the grid size becomes 
large, if those generic filters are also available on VTK you can also replace 
the simple filters (that you are using now) and achieve the same performance 
as paraview.
