A reproducible example would help but indexing with dask arrays is a bit limited.

On https://github.com/pydata/xarray/pull/5873 it's possible it will raise an error and ask you to compute the indexer. Also see https://github.com/dask/dask/issues/4156

EDIT: your slowdown is probably because it's compuing Sn multiple times. You could speed it up by calling compute once and passing a numpy array to isel
