Summary0006066: (MARS-high) ParaView is slow with large AMR CTH data
DescriptionParaView is very slow when operating on large AMR CTH data. We believe this is related to the number of blocks in the hierarchical dataset (thousands to millions)

This is when performing actions such as threshold, point to cell, contour, and calculator, not when rendering.

The high-priority filters are:

1. CellToPoint/Dual grid (to enable isosurface and clip by scalar)
2. Calculator (to make the 3 vector components into a vector)
3. Threshold
4. Clip By Scalar
5. Contour

6. Geometry extraction (vtkPVGeometryFilter?).

Recently I used ParaView to load a multiblock data set that took about a minute to get to the point where an image could be created (and only a small fraction of that was taken in rendering) where a simple VTK program that used vtkCompositeDataGeometryFilter was finished in seconds.

I won't go so far as to say this has been completely resolved, but a lot of work has been done to make AMR data sets with large numbers of blocks process faster.

Further improvements will probably have to be done on a filter or component basis. You should raise a separate bug for each thing that needs to be optimized.

Bug closed. Pat on the back to the team over the last year!
