Key Points
A fundamental tension exists between software performance and flexibility. On the 20% of your software that executes 80% of the time, performance often comes first at the expense of flexibility.
Caching opportunities may surface in the overall program design as well as in the minute coding details. You can often avoid big blobs of computation by simply stashing away the result of previous computations.
The use of efficient algorithms and data structures is a necessary but not sufficient condition for software efficiency.
Some computations may be necessary only on a subset of the overall likely execution scenarios. Those computations should be deferred to those execution paths that must have them. If a computation is performed prematurely, ...
