  "message": "perf stat: add perf stat -B to pretty print large numbers\n\nIt is hard to read very large numbers so provide an option to perf stat\nto separate thousands using a separator. The patch leverages the locale\nsupport of stdio. You need to set your LC_NUMERIC appropriately, for\ninstance LC_NUMERIC\u003den_US.UTF8. You need to pass -B to activate this\nfeature. This way existing scripts parsing the output do not need to be\nchanged. Here is an example.\n\n$ perf stat noploop 2\nnoploop for 2 seconds\n\n Performance counter stats for \u0027noploop 2\u0027:\n\n        1998.347031  task-clock-msecs         #      0.998 CPUs\n                 61  context-switches         #      0.000 M/sec\n                  0  CPU-migrations           #      0.000 M/sec\n                118  page-faults              #      0.000 M/sec\n      4,138,410,900  cycles                   #   2070.917 M/sec  (scaled from 70.01%)\n      2,062,650,268  instructions             #      0.498 IPC    (scaled from 70.01%)\n      2,057,653,466  branches                 #   1029.678 M/sec  (scaled from 70.01%)\n             40,267  branch-misses            #      0.002 %      (scaled from 30.04%)\n      2,055,961,348  cache-references         #   1028.831 M/sec  (scaled from 30.03%)\n             53,725  cache-misses             #      0.027 M/sec  (scaled from 30.02%)\n\n        2.001393933  seconds time elapsed\n\n$ perf stat -B  noploop 2\nnoploop for 2 seconds\n\n Performance counter stats for \u0027noploop 2\u0027:\n\n        1998.297883  task-clock-msecs         #      0.998 CPUs\n                 59  context-switches         #      0.000 M/sec\n                  0  CPU-migrations           #      0.000 M/sec\n                119  page-faults              #      0.000 M/sec\n      4,131,380,160  cycles                   #   2067.450 M/sec  (scaled from 70.01%)\n      2,059,096,507  instructions             #      0.498 IPC    (scaled from 70.01%)\n      2,054,681,303  branches                 #   1028.216 M/sec  (scaled from 70.01%)\n             25,650  branch-misses            #      0.001 %      (scaled from 30.05%)\n      2,056,283,014  cache-references         #   1029.017 M/sec  (scaled from 30.03%)\n             47,097  cache-misses             #      0.024 M/sec  (scaled from 30.02%)\n\n        2.001391016  seconds time elapsed\n\nCc: David S.
