Is this different from caches? If so, the advice also applies to properly using the cache. I've read that cache misses are the biggest source of slow-downs on modern processors. (Sorry, no citation)

This is related to caches as the author is talked about hardware prefetching from memory to caches, i.e., is the act of fetching in to the cache the data that will be needed in the near future. This reduces cache misses.
