Règles de programmation web

Rule 1. You can’t tell where a program is faint to spend its time. Bottlenecks occur un surprising places, so don’t try to second guess and put in a speed hack until you’ve proven that’s where the bottleneck is.

Rule 2. Measure. Don’t tune for speed until you’ve measured, and even then don’t unless one part of the code overwhelms the rest.

Rule 3. Fancy algorithms are slow when n is small, and n is usually small. Fancy algorithms have big constants. Until you know that n is frequently going to be big, don’t get fancy. (Even if n does get big, use Rule 2 first.)

Rule 4. Fancy algorithms are buggier than simple ones, and they’re much harder to implement. Use simple algorithms as well as simple data structures.

Rule 5. Data dominates. If you’ve chosen the right data structures and organize things well, the algorithms will almost always be self-evident. Data structures, not algorithms, are central to programming.
