Summary

0014866: CAM data is unacceptably slow

Description

CAM data is unacceptably slow. Although I don't pretend to understand what it is doing, we are spending lots of time in the area of vtkGeometryRepresentationWithFace object.

Two datasets - Sandia-CAM-Data-Alan1-Do-Not-Release.nc and Sandia-CAM-latlon-Alan1-Do-Not-Release.nc. Ask me for these datasets. (Note to self - CAM-data, on Linux big drive)

* Linux, master, local server.
* Cam NetCDF (Unstructured) reader. Sandia-CAM-Data-Alan1-Do-Not-Release.nc. Connectivity File Name: Sandia-CAM-latlon-Alan1-Do-Not-Release.nc. Turn on Single Level, turn off Cell Layer Right. Apply.
* Color by TQM.
* Play.

Slow, slow, slow. Here is a Timer Log:
