What are the different synchronization techniques and their performance?

What are the different synchronization techniques and how do they compare in terms of performance?

There are several synchronization techniques, including mutexes, semaphores, and monitors. Each has its own performance characteristics depending on the use case.

Can you explain how mutexes work and their performance implications?

Mutexes are used to ensure that only one thread can access a resource at a time. They can lead to performance bottlenecks if not managed properly, especially in high-contention scenarios.

What about semaphores? How do they differ from mutexes?

Semaphores allow multiple threads to access a resource up to a certain limit, unlike mutexes which allow only one. This can improve performance in scenarios where multiple accesses are safe.

Which technique is generally the fastest?

It depends on the specific use case, but generally, mutexes can be faster in low-contention situations, while semaphores may perform better under high contention.
