[Paraview] Paraview performance

[Alberto Fernandez]

I have a question regarding paraview performance. I'm using paraview to 
visualize CFD results. The results are written in ensight format as 
ascii. I have been doing some work on a model with a unstructured mesh 
of about 1.5 million cells. Using simply a clip filter cutting with a 
scalar takes a lot of time. It is not big for just a frame but we are 
calculating 20 time steps. If we want to calculate that cliping (to find 
a free surface) to create an animation it takes about 15 or 20 minutes. 
The machine is an AMD athlon with  4 GB.
We are interested in processing a calculation with around 5 million 
cells. We have tried and it takes hours.
Is there a way of improving this performance through some settings or 
similar?
Does having the results written in ascii (it takes quite some room) have 
some effect on performance?
