What are the performance issues related to spinlocks?
Spinlocks can lead to performance degradation due to busy-waiting, which consumes CPU cycles and can cause contention.
How do spinlocks compare to mutexes in terms of performance?
Spinlocks are generally faster than mutexes for short critical sections, but they can cause more overhead under high contention.
What scenarios should I avoid using spinlocks?
Avoid using spinlocks in scenarios with long wait times or high contention, as they can lead to CPU resource wastage.
Are there any alternatives to spinlocks?
Yes, alternatives include mutexes, reader-writer locks, and atomic operations, depending on the use case.
Can you explain how to implement a spinlock?
Sure! A basic spinlock can be implemented using atomic variables to indicate lock status and a loop to wait for the lock.
