This is just for the purpose of exploring what takes the most time in the evalscript that is generated from process graph as part of Open-EO/openeo-sentinelhub-python-driver#27.

The most time-consuming tasks are

  • ndarray function
    • consequently DataCube constructor
  • filter_temporal process (filter_temporal.js)
  • reduce_dimension process (reduce_dimension.js)
  • aggregate_temporal (aggregate_temporal.js)
  • others from src/pg_to_evalscript/node.py

These consume upwards of 10ms (=> should be multiplied by the number of pixels in the requested area to get approximate time these consume for the whole returned image)
