Following-up my previous post on how to increase site performance. I received an email from my lead about a Firefox add-on named “Page Speed” that helps analyze a site performance.

In brief, Page Speed is an open-source Firefox/Firebug Add-on. Webmasters and web developers can use Page Speed to evaluate the performance of their web pages and to get suggestions on how to improve them.

Page Speed works by performing several tests on a site’s web server configuration and front-end code. These tests are based on a set of best practices known to enhance web page performance. Webmasters who run Page Speed on their pages get a set of scores for each page, as well as helpful suggestions on how to improve its performance.

But that’s not all, the good stuff is its article “Performance Best Practices” which explains in detail all aspects on what needs to be done to improve your site: from network (DNS, server settings) to browser layer (CSS, JavaScript, image, compression) which extends my previous post in greater detail.

However these best practices may not be the complete solutions, in my opinion. If your site deals with dynamic content, there should be programming logic behind the content. This means whoever creates the logic has to utilize the best logic for highest efficiency in terms of computation. And if your site deals with a database, optimizing the queries to the designated database is also required.

Ultimately basic rules for programming are to avoid redundancy and to distribute computation load whenever possible.
