When should I use spinlocks in my code?

What are spinlocks and when should I use them in my code?

Spinlocks are synchronization primitives that allow threads to wait in a loop (or 'spin') while checking for a condition. They are useful in scenarios where the wait time is expected to be very short.

What are the advantages of using spinlocks over other locking mechanisms?

Spinlocks can be more efficient than traditional locks in low-contention scenarios because they avoid the overhead of context switching. However, they can waste CPU cycles if the wait time is long.

Are there any downsides to using spinlocks?

Yes, spinlocks can lead to CPU resource wastage if a thread spins for too long. They are not suitable for high-contention situations or when the wait time is unpredictable.

In what situations would you recommend using spinlocks?

Spinlocks are recommended in real-time systems or low-level programming where the lock hold time is minimal, and the overhead of context switching needs to be avoided.
