Thanks Vincent. Can you afford doing a capture of `perf record` and share the resulting perf.dat with vmlinux (with debug symbols)? Having a before/after capture would be even better. Not sure if we can do much about this -1.61% in your case, but it'd be good to understand why if possible. perf bench sched pipe is very sensitive to tiniest of changes which could be due to binary-to-binary differences.
