Hi Ali, Thanks for the hint. But these numbers would be approximate, since part of them won't commit. Is that correct? About Yongbing's point: I am also observing a huge difference between those numbers. I was thinking maybe we should compare that number with commit.committedOps, rather than commit.committedInsts. Please let us know your comments.
Thanks.
