Summary0014866: CAM data is unacceptably slow
DescriptionCAM 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 - and Ask me for these datasets. (Note to self - CAM-data, on Linux big drive)

* Linux, master, local server.
* Cam NetCDF (Unstructured) reader. Connectivity File Name: Turn on Single Level, turn off Cell Layer Right. Apply.
* Color by TQM.
* Play.

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

I thought there was an issue with parallel, where the more servers the slower ParaView ran, but cannot replicate it. Since I now believe we can always throw multiple servers at the problem, this bug is not a crisis.

I believe time is being spent in OpenGL. This runs well with a graphics card - but very slow software rendered (NX). Thus, it is a user problem - i.e., use hardware rendering!

Closing this bug. I will open it again if I find it is a problem.

My bad. I wanted to close this bug. Closing.
