}

它运行timer以调用timerCallback（。。）以特定的频率周期性地。在本例中，必须每秒调用5000次回调。一个人可以玩频率，并看到实际（测量）的呼叫频率不同于期望的频率。事实上，频率越高，偏差就越大。我用不同的频率做了一些测量，下面是总结:https://docs.google.com/spreadsheets/d/1sqtg2slnv-9vpdgs0rd4ykrnydk1ijkrjvz7bbmsg24/edit?usp=sharing

当期望频率为10000Hz时，系统漏报率为10%(～1000)。当期望频率为100000Hz时，系统漏报率为40%(～40000)。

问题:在Linux\C++环境中有可能实现更好的精确度吗？怎么做？我需要它的工作没有显著的偏差与频率500000Hz

附注。我的第一个想法是它是timerCallback的主体（。。）方法本身会导致延迟。我量过了。它的执行时间不到1微秒。因此它不会影响进程。
