    Status: Open => Answered

Gary Pekmezi proposed the following answer:
The first thing I notice, is that there is only 1 mpi process for
python, so only 1 core. I don't believe there will be any speedup with
only one core beyond maybe 2-3 simultaneous processes.

One other thing to consider, is setting the environment variable
OMP_NUM_THREADS before running the mpiexec command.
