: On another set of lmbench runs (no low-priority processes), I got:
: "size=0k ovr=6.23
: 2 5.12
: 2 3.97
: 2 3.96
: 2 3.94
:
: yet a second later I got:
: "size=0k ovr=6.23
: 2 5.12
: 2 5.12
: 2 5.13
: 2 4.35
:
: so it's not hard to find a 30% variance in lmbench either.

That's weak. You'll be hard pressed to find a consistent variance
in that benchmark. Go run it 10 times in a row and tell us what the
variance is. I just did it and got 12%. On the other hand, you've been
telling us all along that your tests varies 70-100% every run. If you
had started out the conversation: I ran ten times and go one case that
was off by a 100%, but the rest all nicely clustered around one point,
I don't think anyone would have had an issue, now would they?
