This is the correct answer. Never assume anything about performance
before having tested it.

This is very frequently the correct answer to these questions!
Never assume ref is faster if speed matters - it may not be.

Smart optimizer should think for you without any "auto" private
words if function is inlined. I mean LDC compiler first of all.

I am creating Vector3 structure. I use struct to avoid GC.
However, struct will be copied when passed as parameter to
function
struct Ray {
Vector3f origin;
Vector3f dir;
@nogc @system

this.origin = *origin;
