A counting semaphore resembles a mutex in several respects, but there are differences, as
well as reasons to use one resource over the other.
A mutex is exceptionally robust in providing mutual exclusion. If this is crucial to
your application, then using a mutex is a good decision. However, if mutual exclusion is
not a major factor in your application, then use a counting semaphore because it is
slightly faster and uses fewer system resources.

计数信号量与互斥锁对比
本文探讨了计数信号量与互斥锁在提供资源管理方面的相似性和区别。互斥锁在确保互斥访问方面表现出强大的能力，适用于需要严格同步的应用场景。然而，如果应用程序中互斥不是主要考虑因素，使用计数信号量则更为合适，因为它在速度上稍快且消耗较少的系统资源。
