The not-so-great news is that I see that just adding perf tracepoints (not even enabling them!) seems to make a small diff (3 Gbps vs 3.2 Gbps) to my numbers. Is that mere standard-deviation, or something one should be aware of, about perf?
existence of traepoints has no overhead until activated (ie., launch perf or start ftrace for those tracepoints).
