换句话说，当许多线程都想访问共享资源时，JVM可以花更少的时候来调度线程，把更多时间用在执行线程上。

In other words, when many threads are attempting to access a Shared resource, the JVM will spend less time scheduling threads and more time executing them.

多线程计算不仅用来实现细粒度的并行，合理的调度策略还有助于隐藏通信延迟。

Multithreads can not only implement fine-grain parallelism effectively, but also be helpful to hide communication latency with reasonable scheduling strategies.
