The article demos a list, where threads are contending to append to the top of it. Unlike a list, there is not much contention on a FIFO unless its typically empty..

You are correct, I meant lifo but wrote fifo.

OSEnqueueAtomic/OSDequeueAtomic and InterlockedSList, by virtue of only being able to push and pop the head, are effectively LIFOs.
