On a customer benchmark I am measuring read_csv is significantly slower with the default client rather than with the configured one.

read_csv: 13.72040319442749  # Client() # worker threads and processes take place
read_csv: 3.934723377227783  # Client(n_workers=16, threads_per_worker=1) # pure multiprocessing

We can set DaskThreadsPerWorker to 1 to get pure multiprocessing in Dask.
