OpenBLAS: daxpy 10x slower on macOS (Haswell)
Calls to daxpy seem to be about 10x slower on macOS than when run inside a Linux VM on the same machine (both give the config as “USE64BITINT DYNAMIC_ARCH NO_AFFINITY Haswell”).
This affects a lot of code which depends on it (e.g. dgebrd).

I have emailed @xianyi about adding more people as admin and perhaps even moving the project to an OpenBLAS organization to help maintain it better.
Tagging for 0.3.0 as xianyi created that milestone recently, hopefully the release will happen soon.
