Check the linked video, it's a great talk on memory access patterns and why it matters. If you already know "everything" about it, then I guess there's not much new in my article but if you're like many of my co-workers, ordinary web developers some of this might come as a surprise. I think performance optimization overall is under-appreciated in the wider development community, too many devs expect the runtime/compiler to solve it for them.
