而言，表现为顺序执行的程序，它并没有由于引入多 线程而得到任何效率上的收益。对此有什么办法能够适当的加速呢？答案便是削弱原子操作的在进程间 的同步条件。 从原理上看，每个线程可以对应为一个集群节点，而线程间的通信也几乎等价于集群节点间的通信。 削弱进程间的同步条件，通常我们会考虑四种不同的一致性模型： 1. 线性一致性：又称强一致性或原子一致性。它要求任何一次读操作都能读到某个数据的最近一次写 的数

the current thread?Why do we need to move work off the current thread? Many environments have a dedicated thread for processing events: GUIs Client-Server applications Performing extensive processing to a dedicated background threadHow do we move work off the current thread? Possible ways to move the work off the current thread: Spawn a new thread for each event handler Pass data to a dedicated background move the work off the current thread: Spawn a new thread for each event handler Pass data to a dedicated background thread Submit tasks to a generic thread pool Submit tasks to a special purpose executorSpawning
