In situations where reads greatly outnumber writes, volatile variables may also provide a performance advantage over locking.

在某些情况下，如果读操作远远大于写操作，volatile变量还可以提供优于锁的性能优势。

Unlike locking, volatile operations will never block, so volatiles offer some scalability advantages over locking in the cases where they can be used safely.

volatile操作不会像锁一样造成阻塞，因此，在能够安全使用volatile的情况下，volatile可以提供一些优于锁的可伸缩特性。
