Paraview extremely slow on workstation


I have a linux workstation but paraview on it is extremely slow… I have no idea of why this happens but a difference of 100-150x is noted w.r.t. a normal laptop

Could you help me troubleshooting it?

Best regards

What is slow? The UI? Rendering? Can you test a Python script to see if it is also affected?

Could you share a “benchmark” python script that can be useful to understand where the issue is?

The ParaView binary release form comes with a small benchmark.

See the

Also, please go to Help/ About, and post a screenshot. Is ParaView running in hardware rendering?

The test were performed but they are not so heavy hence were smoothly processed. I have issues for 3d files.

The about is:

@mwestphal Do I read this correctly that he is running in Mesa? That would be the issue?

I’m never used an AMD so I’m not enterely sure but to me it looks like the GPU is being used.

What should I do to use only CPU? May it be faster? I have 32 cores

Hi Mathieu,
I’m also having issues with Paraview being too slow when I want to visualize the 3D model results on Paraview.
When I ran ‘glxinfo | grep Vendor’, it said:
Vendor: Mesa/ (0xffffffff)
Does that mean that my Paraview is running with Mesa? If yes, is that the reason why my Paraview is running so slowly? Thank you!
