[Paraview] Excessive memory consumption when loading a series of VTK legacy files

[Roman Geus]

Hello all

I am using ParaView 3.2beta in client/server mode with remote rendering 
(threshold=0m).

When loading a series of VTK legacy files (*.vtk) as described in 
http://paraview.org/Wiki/Animating_legacy_VTK_file_series I'm 
experiencing excessive memory consumption on the client side.

Here is a table that shows the memory consumption on the client and the 
server depending on the number of timesteps:

time steps  client memory  server memory
        100            38m           140m
        200            44m           140m
        500            95m           160m
       1000           276m           240m

(each VTK file is 2m size)

Clearly the client will eventually run out of memory when the time steps 
are further increased.

I don't understand why the client uses so much memory, when all the data 
reading and rendering is done on the server.

Can somebody shed some light into this?

Is this a general problem with time steps or is it just with VTK legacy 
files?

Thanks and best regards,
Roman
