High Performance Web Site by Steve Souders
Internet users often expect that your website will respond quickly, if not, they will leave and move on to one of your competitors. Companies like Google and Yahoo! knows this and one of the reasons why they perform so well, is Steve Souders.
The techniques used in this book are fairly easy to implement and if you have been reading my blog for some time, then you already know a few tricks. Some of them are that you can reduce http requests with css sprites and that you could/should place javascript at the bottom of the page.
There are 14 steps in this book on how to make your website perform better, so if you are into this, I strongly recommend you to read it.
