ParaView builds VTK with thread parallelization support while the official python wheels of VTK have this option turned off see [here](https://discourse.vtk.org/t/are-there-any-prebuilt-python-wheel-with-openmp-support). This is why ParaView is faster. You can try the same script in `pvpython` the python interpreter that comes with ParaView itself.
