Here. == Performance counter stats for './runpause.sh' (5 runs): 475884.969949 task-clock-msecs # 7.913 CPUs ( +- 0.005% ) 36592060 page-faults # 0.077 M/sec ( +- 0.301% ) 3037784893 cache-references # 6.383 M/sec ( +- 0.361% ) (scaled from 99.71%) 1130761297 cache-misses # 2.376 M/sec ( +- 0.244% ) (scaled from 98.24%) 60.136803969 seconds time elapsed ( +- 0.006% ) == But this program is highly affected by cpu utilization etc...
