Do bagpipes explain the mystery of sand performing calculations and taking actions? Do they give you an intuition for connecting how CPUs and memory accesses and cache hierarchies work with high level code, in such a way that you can start to understand why one version of code might be faster or slower than another?

If you can't see through field accesses and function calls to memory indirections, anything you might read about how TLBs and caches and branch prediction work doesn't connect to much.
