i think these last few posts have been kindoff off topic but i will comment anyway: a well configured system run by an informed if not well trained user will work significantly better than a hack banging away changing stuff they know nothing about and trying to use the system anyway they want.
that applies i think weather you are using any variant of windows, linux, amiga os or mac os
think of it like a car: if you put kero in, set tire presure to 90lbs and run your standard tranny like an auto and leave your doors open for air; you arent going to go too far no matter how you think it should be setup.
