[Paraview] line filter is slow with xmf in parallel

[Anthony Ruiz]

Hi,

I have a python script that creates multiple 1D lines and export them
to csv files. When I load my xmf data in parallel, the script is very
slow and every line takes about 30 minutes to be exported to csv.

When the same data is loaded with a vtm input file in parallel, it's
very fast (less than 10 secs per line).

Is it expected?

In both cases, my pipeline is:
input file (vtm or xmf)
mergeblocks
celldata2pointdata
  line1
  ...
  ...
  linen
