A spinlock is the fastest and most simple thread lock mechanism available.
It is very efficient since it does not use any operating system calls; it is only a test and set on an atomic variable, thus it is the fastest thread lock available. Spinlocks are efficient if threads are only likely to be blocked for a short period of time, as they avoid overhead from operating system process re-scheduling or context switching. However, spinlocks become wasteful if held for longer durations, both preventing other threads from running and requiring re-scheduling.
