@jakirkham and @charlesbluca have successfully implemented nightly cythonized builds for Distributed. Folks can test in a new or existing environment with following snippet:

mamba/conda install -c dask/label/dev distributed-impl=*=*cython

The goal for cythonizing the scheduler is to improve performance where the number of tasks is so large that the scheduler itself becomes a bottle neck

In addition to announcing here would anyone object to me sending out a tweet ?
