The article mentioned testing on macOs and Linux implementations. I was curious and I tried the author's demo program on Windows Subsystem for Linux; it performs quite well, running almost instantly on a low-end Surface 3.

Its definitely interesting to see these very low-level implementation details bubble up to the surface from time to time.

I find the optimizations tend to derive from real use cases.

In this case, both Windows and Linux are used for huge server farms. MacOS not so much. Apple probably doesn't spend the energy optimizing this sort of thing since it's less likely to cause trouble for them.
