you can use the PEBS events to gather aggregate stats though and they seem roughly right. Are they truly meaningless? I had misremembered that they might not have the determinism problems of regular events (turns out that's wrong). They oddly seem to be worse in some limited tests I did. So I guess nothing will be lost if they're disabled. Vince
