yep, it's taken into account:
[jolsa@krava perf]$ ./perf record --output result_1 --dir ./perf bench sched messaging Couldn't synthesize bpf events. # Running 'sched/messaging' benchmark: # 20 sender and receiver processes per group # 10 groups == 400 processes run
Total time: 0.177 [sec] [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.316 MB result_1 (7225 samples) ]
[jolsa@krava perf]$ ll result_1/ total 348 -rw-------. 1 jolsa jolsa 27624 Feb 4 11:35 data.0 -rw-------. 1 jolsa jolsa 56672 Feb 4 11:35 data.1 -rw-------. 1 jolsa jolsa 30824 Feb 4 11:35 data.2 -rw-------. 1 jolsa jolsa 49136 Feb 4 11:35 data.3 -rw-------. 1 jolsa jolsa 22712 Feb 4 11:35 data.4 -rw-------. 1 jolsa jolsa 53392 Feb 4 11:35 data.5 -rw-------. 1 jolsa jolsa 43352 Feb 4 11:35 data.6 -rw-------. 1 jolsa jolsa 46688 Feb 4 11:35 data.7 -rw-------. 1 jolsa jolsa 9068 Feb 4 11:35 header
