It depends on whats running at the time... with some light load, i measured wall clock time, i remember seeing 2 secs at times, but its been a long time i did that.. so take that with a pinch :-)_
i will try to get those idle and load times worked out again... the best i have is a 16 way, if i get help from big system oems i will send the numbers out > > I assume it must take much longer, else you wouldn't have written the code. > Have you any ballpark numbers for how long it _does_ take?
