Development #3

Favor static pages

If a page only needs to be changed twice a year, use a static page built outside of the CMS. This reduces CPU usage, bandwidth and electricity consumption.
That is because dynamic content management systems must load the various software layers to serve the content requested by the user — e.g. the HTTP server, applications server, content storage system (database) — and, potentially, related cache systems. On the other hand, a static file is directly read and sent to the user by the HTTP or cache server, skipping the need for the application server or database.

Development #37

Use local variables

When you call a global variable in JavaScript, the interpreter must check that:
- it exists in the current scope, in the scope above, etc. - the variable has a value - and more

To avoid all these checks, it is often possible to make useful variables local by transforming them into routine arguments. This process saves CPU time.
