As a general rule I wouldn't worry too much about test speed. Speed is extremely dependent on exact workloads. And this is doubly so for test suites -- production workloads tend to do a small number of normal things over and over, while a good test suite never does the same thing twice and spends

Heya, I'm not a numbers guy, but I maintain servers for scientists and researchers who are. Someone pointed out that our numpy installation on a particular server was only using one core. I'm unaware of the who/how the previous version of numpy/OpenBLAS were installed, so I installed them
