This reminds me of David Wheeler's adage: All problems in computer science can be solved by another level of indirection. The rejoinder, and I don't know who gets credit for it, is: All performance problems can be solved by removing a layer of indirection.

An often cited corollary to the first one is, "...except for the problem of too many layers of indirection." :) https://en.wikipedia.org/wiki/Indirection https://en.wikipedia.org/wiki/Indirection

  Incorrect: that problem, too, can be solved by adding another layer of indirection - then adding an optimized implementation underneath it.

Have we stopped solving all performance problems with introducing a cache? Why wasn't I told? Will I have to hand in my union card?
- infogulch 6y ago
  No worries, your union card is safe: a cache is just a particular kind of added indirection. :)

    And some architectures have magically improved performance by reconfiguring caches as scratch pad memories. http://rexcomputing.com/ http://rexcomputing.com/
