Improve the CGNS reader to reduce loading time
Improve the CGNS reader to reduce loading time of large datasets. This would be useful for post-processing large datasets in all applications such as CFD where the CGNS format is widely used.
With a medium size 1.4 Gb CGNS dataset, Tecplot loading time is about 15 times less than the loading time of the VisIt CGNS reader in PV 4.0.1.
The reader has undergone several improvements in recent releases (e.g. 5.4). Please give it a try and report issues if run into (the mailing list or the issue tracker ( https://gitlab.kitware.com/paraview/paraview/issues) might be easier for that.
