| |
Description of --no-aggr in perf-stat man page is outdated. --no-aggr can also be used while profiling specific set of cpus. For ex,
$ perf stat -e cycles,instructions -C 1-2 --no-aggr -- sleep 1
Performance counter stats for 'CPU(s) 1-2':
CPU1 5,94,92,795 cycles CPU2 2,69,72,403 cycles CPU1 2,02,08,327 instructions # 0.34 insn per cycle CPU2 73,17,123 instructions # 0.12 insn per cycle
1.000989132 seconds time elapsed
