Here is what I learned: * The same tests are slow in windows and linux. Just, that those on windows take about twice as long. * The following test seem to be slow: * xarray/tests/test_distributed.py * many tests with sparse, e.g. xarray/tests/test_dataset.py::TestDataset::test_unstack_sparse * plotting tests, especially with FacetGrid

I am not sure what takes long in xarray/tests/test_distributed.py: writing the files or creating the cluster. If it is the latter, it could be possible to only open in once in the module (but I don't know if that actually works or if it has to be closed every time).
