I modified the Go version to pass references (see my second edit) and that made up the difference (or I mistranslated).

  Ah, you replied to my comment before the edit, about unnecessary allocation in Go vec handling.

    I'm 99% sure the Go version doesn't allocate any vectors; afaict, it's passing everything on the stack.
