[Paraview] How to interpret timer log

[David E DeMarle]

I counted more than one question (six in fact) in that last email. :)

I believe the 3.029 seconds includes the transfer time, but I may be
incorrect on that. Someone please correct me if I am wrong.

While you drag the mouse and move the camera paraview does interactive
renders. Iteractive renders will (depending on data and the preference
settings) use subsampled geometry and subsampled images. Once you release
the mouse, ParaView does a still render at full resolution.

See answer to question 1, the MPI time (and processing) is being counted as
part of the rendering. Since it is "part of" the rendering, it shows up
after in the log (even if it happened first).

Geometry (the surface of whatever your data is).
