Studies have shown that if a web site takes more than 8-10 seconds to load on a 56k modem then you risk losing the visitor. This means that the web page design needs to be less than 30 kilobytes in size. There are four main areas that need to be considered when building a web site:
Every web page design has a certain amount of back-end ‘code’. The volume of code produced, to make your web site work, significantly impacts on the loading time. However, there are a number of techniques you can employ to minimise the size of your code (such as CSS-based web site layouts and HTTP compression).
