from Camarade_Tux Not completely true. In fact, BSD and probably Linux use more RAM than any windows : they use as much RAM as possible. the way that linux runs its program is more HARD on the memory BUT .. heres the killer if there is a Kernal UP it can be DONE without the need for restarting the PC for the changes to take place and its loads the programs into memory which helps on the speed thats if i can recall right ... yes: the *NIX ( BSD / Linux ) use more memory but once you closed that program ... its feee up back up
