What is the performance of semaphores in concurrent programming?
Semaphores are synchronization tools that control access to shared resources. Their performance can vary based on implementation.
How do semaphores compare to mutexes in terms of performance?
Semaphores can be more flexible than mutexes, allowing multiple threads to access a resource, but they may introduce more overhead.
What factors affect the performance of semaphores?
Factors include the number of threads, the frequency of resource access, and the underlying system's scheduling policies.
Can you give an example of semaphore performance in a real-world application?
Sure! In a web server, semaphores can manage access to a limited number of database connections, optimizing resource use.
