[Paraview] Paraview Tiled-screen mode with client-renderserver-dataserver blocked

[Utkarsh Ayachit]

There may be some issue with tile display with pvrenderserver. In
general, I'd recommend using pvserver. For reducing the slowness try
playing with the following settings  in the Edit | Settings dialog
(Render  View | Server Page) (I am assuming, the slowness you are
referring to is during interaction):

* Interactive Subsample Rate: Try increasing this. This will render
smaller images while interacting, thus reducing the load during
interaction. Generally this does the trick.
* Remote Render Threshold: Try unchecking this. For large screens,
smaller datasets, compositing may be the costlier operation. Instead
switch to data-duplication mode, in which call all tiles render the
data locally.
* Still Subsample Rate: Try checking this and experimenting with
setting the smallest value for which you get decent performance. This
controls the subsampling used for non-interactive renders. Generally
you want this to be full resolution, but if performance becomes an
issues, you can tweak this parameter.

Hope that helps.
