I have tried the old-fashioned method of peppering timing statements everywhere in the python script, but it is very tedious and hasn’t led me to the source of the issue. I was wondering if anyone has any suggestions for how to run a Paraview python script through a more advanced software profiler i.e. has anyone profiled the performance of Paraview as it executes a python script?
