When tasked to improve a web app's performance, the first thing that
developers often do is tweak the backend - web server, database, for
example. But according to the Yahoo! Exceptional Performance Group,
most optimization opportunities exist after the requested page has
been given to the browser. For example, when a URL is entered into the
browser, 62% to 95% of the time is spent fetching the images, CSS,
JavaScript contained in the page.

As a result of their study and experiment, the Yahoo! team has
identified 13 rules to improve website performance. To know which of
these rules you have violated, you can use YSlow, a Firefox add-on
that works with Firebug. If you're not using Firebug, you're missing a
lot :)

I have also written a short piece why users say your website is slow.
