Can you explain how spinlocks work in multi-threading?
Sure! Spinlocks are a type of synchronization mechanism used in multi-threading to protect shared resources.
What makes spinlocks different from other locking mechanisms?
Unlike traditional locks, spinlocks keep checking the lock status in a loop (spinning) until it's available, which can be efficient for short waits.
Are there any downsides to using spinlocks?
Yes, if a thread holds a spinlock for too long, it can waste CPU cycles and lead to performance issues, especially in high-contention scenarios.
When should I use spinlocks instead of mutexes?
Use spinlocks when you expect the wait time to be very short and want to avoid the overhead of putting a thread to sleep.
