"Applied Complexity" at its best?

I can think of various analogues to this in computer science. One is profile guided optimization, where instrumentation is added to a code so that it records where it has been. Then those records are used to guide refinement of the compilation of the code so that it anticipates where it is likely to go. For example, prefetching data, or setting branch probability hints in the code. This is in some sense Amazon prefetching their deliveries so that they will be in cache (near the likely buyer) should the buyer actually ask for them. Some advanced database systems (or just database administrators) do the same thing for large systems -- looking at who tends to use certain tables, and making sure those users are near their data.
