We've recently seen that Parcels can sometimes be very slow on python3. After some digging around, we think that this is related to a recent upgrade of the netCDF4 package. We therefore suggest to avoid using v1.4.2 of the netCDF4 package, especially if you're using python3.

The plan now is to wait for a future update of netCDF4, and see if that fixes the slowness.

Does one has to limit the netcdf version of the environment ? like a downgrade via conda-forge? or is this a parcels intern issue - if the case how can I downgrade the netcdf version there? Thanks in advance!
