For fun and frolics:

No flags: 1843ms

-march=native: 2183 ms

-O2: 423 ms

-O2 -march=native: 250 ms

-O3: 425 ms

-O3 -march=native: 255 ms

O3 doesn't seem to be helping in my case.

Yeah, I was just trying to show the difference. Doing it without optimisation flags is an utterly bewildering decision by the author.

Especially given the goal was increasing performance.
