  • Absolute speed of xhistogram appears to be 3-4x higher, and that's using numpy_groupies in flox. Possibly flox could be faster if using numba but not sure yet.

Could you show the example that's this slow, @TomNicholas ? So I can play around with it too.

One thing I noticed in your notebook is that you haven't used chunks={} on the open_dataset. Which seems to trigger data loading on strange places in xarray (places that calls self.data), but I'm not sure this is your actual problem.
