SpinWait

At the beginning of this chapter, we mentioned that spinning is much more efficient than blocking for smaller waits. Spinning has fewer kernel overheads related to context switching and transitioning.

We can create a SpinWait object as follows:

var spin = new SpinWait();

Then, wherever we need to make a spin, we can just call the following command:

spin.SpinOnce();

SpinLock

Locks and interlocking primitives can significantly slow down performance if the wait time to get a lock is very low. SpinLock provides a lightweight, low-level alternative to locking. SpinLock is a value type, so if we want to use the same object in multiple places, we need to pass it by a reference. For performance reasons, even when SpinLock...
