When should I use mutexes instead of spinlocks?

Mutexes are generally preferred when you expect threads to be blocked for a longer time, as they can put the thread to sleep.

What are the advantages of using mutexes?

Mutexes can reduce CPU usage by allowing threads to sleep, which is beneficial in scenarios with high contention.

Are there situations where spinlocks are better?

Yes, spinlocks can be more efficient for short critical sections where threads are unlikely to be blocked for long.

How do I decide which one to use?

Consider the expected wait time and contention level; use mutexes for longer waits and spinlocks for short, frequent access.
