Ok, we are on the same page then.

in case I confused anyone, the reason I went into detail on the hardware 
side of things was to explain how proper hardware selection could result 
in good performance while poor hardware selection would result is dismal 
performance (and to give people who aren't familiar with the options some 
hints as to what they could do)
