Wow, that is pretty bad.

Try setting compat='broadcast_equals' in the open_mfdataset call, to restore the default value of that parameter prior v0.9.

If that doesn't help, try downgrading dask to see if it's responsible. Profiling results from %prun in IPython would also be helpful at tracking down the culprit.
