1. The first rule of Optimization Club is, you do not Optimize.
  2. The second rule of Optimization Club is, you do not Optimize without measuring.
  3. If your app is running faster than the underlying transport protocol, the optimization is over.
  4. One factor at a time.
  5. No marketroids, no marketroid schedules.
  6. Testing will go on as long as it has to.
  7. If this is your first night at Optimization Club, you have to write a test case.
(Adapted from separate lists by David Fetter and Michael Schwern.)

When you are thinking about rule #2, you reach for Devel::NYTProf.

Rule #7 demands an addition to your test suite, which means delving into Test::More or, if you prefer, Test::Most.

One rule that doesn't fit in the rules format: If your code doesn't do what you want it to do, you have no business optimizing it.
