What are the performance differences between spinlocks and mutexes?
Spinlocks are generally faster for short wait times because they keep checking the lock, while mutexes can block the thread.
In what scenarios would you recommend using spinlocks over mutexes?
Spinlocks are ideal for low-contention scenarios where the wait time is expected to be very short, like in real-time systems.
Are there any downsides to using spinlocks?
Yes, spinlocks can waste CPU cycles if the wait time is long, as they keep the CPU busy checking the lock.
How do I decide which one to use in my application?
Consider the expected contention and wait times. For high contention, mutexes are better; for low contention, spinlocks may be more efficient.
