} What does <20 us mean. Under what load. If it is 10 to 20 I got it with } a stock portable G3 MAC. If I avoided ping -f I could get even less than } 5 us. But it does mean nothing. Yes, low 10's (us) is about typical for Apple hardware. I addressed you specifically because you suggested stock hardware couldn't do that. Now I see that you have seen better than 20us from your stock Apple.
