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`","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,331668890
