OK, thanks. I'm a little surprised that this patch wasn't accompanied by a
problem description, really. I mean, if a single CPU offlining takes three
milliseconds then why bother?
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
Why is taking 30s to offline CPUs a problem?
