Because PREEMPT=n, no differnce between v1/v2, basically.

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...

Thanks,
