[Paraview] Slow with just 1M cells

[Michele Battistoni]

Paraview is awesome for lots of functionalities, however I find it extremely slow in processing data with any filter type, or in changing timestep as soon as the model size is around one million cells or above. I have experience with a commercial tool which on the same model and pc is 100x faster. Let's say a second vs. a min!

Is there any specific settings for ram of parallelization among cores?

Thanks
