But the extrapolation is invalid. gcc does a lot of loading of resources on and off the disk, running external programs, etc. Much of the time that it takes for a small program are taken up by this overhead. The overhead is a "fixed cost," though; it is constant. It becomes insignificant when your project is big enough. -- Erik Max Francis | max AT alcyone DOT com Alcyone Systems | http://www.alcyone.com/max/ San Jose, California | 37 20 07 N 121 53 38 W &tSftDotIotE | R^4: the 4th R is respect "You must surely know if man made heaven | Then man made hell"
