Indeed.  I just did a similar test with my own program on a Pentium 4 2.4 GHz.
In the position after 1. e4 e5 2. d4 d5, my program generates 30 million moves
per second.  I guess I could speed it up somewhat, but I don't think I would
come anywhere close to the speeds reported by Vincent and Angrim.

My move genererator assigns all moves a move ordering score, and also
determines which moves are checks.  It generates legal moves only.

But anyway, I don't understand why people spend so much time and energy on
micro-optimising their move generators.  Despite my slow movegen speed, my
program spends only 1 or 2 percent of its time in the move generator.  I
guess most other programmers have similar numbers.
