Use a lower number of the workers

Browse Source 
Use a lower number of workers rather than the default value, which is
equal to the number of the cpu. Otherwise, in a multi cpu environment,
the number of the processes will very high.

In this PS, we use min(5, << number of cpu >>) as the default worker
count.
