I think the point being that Vincent's post was pure nonsense.  SMT _does_
provide a speed-up.  Not a slow-down as Vincent claimed...

That is where this nonsense started.  I have a dual PIV/2.2 here, I had
already tested on it.  Which is what makes me wonder why Vincent has to
post things that are absolutely and provably wrong, every time...
