Thanks for reporting the issue! This happens because the climate_statistics and extract_levels preprocessor functions are now lazy, but the ESMPy based regridding preprocessor is not. Therefore it was loading the data from disk and recomputing the input to the regridding multiple times. It should be fixed by ESMValGroup/ESMValCore#2418.

(Note: ESMValTool install main branch fails with missing author message -- despite inclusion of authors.)

It looks like you did not install ESMValTool, but only created the conda environment with its dependencies. If you run pip install -e . in the directory where you checked out ESMValTool it should work as expected.

Excellent! Thanks for sorting this out :D
