Yeah, maybe optimal reordering of instructions and branch prediction
too, in combination with register allocation. C# was brilliant at
numerical analysis type performance right from the get-go.


I have a vague memory of .net runtime statistics being stored and used
to optimise subsequent runs of a program, but after a quick google I'm
not sure if I just made that up.

I should try .Net core on Raspbian.
