This is due to an underlying library using the maximum number of available threads to execute a code. This causes drops in performance. When declaring the previous variable, you will only allow one thread per process, thus restoring expected performance.

> Note that trying low values such as `OMP_NUM_THREADS=2` or `OMP_NUM_THREADS=4` may give you better performance.
