开头就讲了CPU Cache 与 Cache Line。
做了三个benchmark：分别是遍历linked-list、行方向遍历矩阵、列方向遍历矩阵。
让我惊奇的是，遍历linked-list比列向遍历矩阵还快，更准确的说，它只比行向遍历矩阵慢一些
> The linked list is twice as slow as the row traversal mainly because there are cache line misses but fewer TLB (Translation Lookaside Buffer) misses. A bulk of the nodes connected in the list exist inside the same OS pages.
