Which code are you talking about? The factored "Doors" code takes less
than 2 ms on my machine (iForth64) and is obviously dominated by I/O.

The referenced page has actually three versions: Factored, Unfactored
and Optimized. I like the last one best, it's easier to add bells and
whistles than to remove them.
