So what?  The part that AKE cited says that it had not become outdated
when the page above was written (which was in 1996 or shortly after).
If it held true for so long, it might still hold true today.  If you
want to know, go out an measure it!  The page contains the measured
code, so it's not that hard.  Current iForth and VFX might do better
(or maybe not), but for everything else I expect that the factor of
2-3 still holds.
