> Link Time Optimization (LTO) and Profile-Guided Optimization (PGO) have a major impact on Python performance: they make Python between 10% and 30% faster (coarse estimation).
>
> Currently, macOS installers distributed on python.org are built with Clang 6.0 without LTO or PGO. I propose to enable LTO and PGO to make these binaries faster.

Oh, I forgot to mention that I discovered that macOS doesn't use LTO when I worked on the https://bugs.python.org/issue39542#msg373230 issue.
