结论: 分布式锁竞争加速比随CPU核数成正比，可以达到和单核多任务时相当的性能，是多核编程的发展方向。 <img src ="aggbug/1800319.aspx" width = "1" height = "1" />Wed, 26 Sep 2007 01:20:00

CriticalSection， OpenMP库带的锁在单任务运行情况下和多任务运行情况下的性能情况，在多核CPU上，多任务的锁竞争花费的时间是单任务时的锁运行花费时间的18倍。锁竞争带来的效率下降完全出乎意料之外，由此也可见多核编程和单核多任务编程是有很大区别的。<img src ="aggbug/1689853.aspx" width = "1" height = "1" />Sat, 14
