Abstract
Spinlocks are described by Microsoft as “lightweight synchronization primitives.” The description looks a lot like the one used for latches, which are described as “lightweight synchronization objects.” This is no coincidence, as spinlocks and latches have a lot in common and both are used to serialize access to internal data structures. Both latches and spinlocks are used when access to objects needs to be held for a very short amount of time.
