Web Design and Mouse Rage Syndrome

Have you ever been frustrated at a Web site that downloads with the speed of an Alaskan glacier? Or become angry when a favorite site, or your Internet connection, is down. Have you experienced any of these symptoms:

  • Faster heart rate?
  • Increased sweating?

In the case of Web page download time, she argues that the backend systems which generate an HTML document -- apache, C++, databases, etc. -- should be regarded as the 80% of causes that account for only 20% of download time. The other 80% of download time is spent fetching the elements that make up the page, such as images, scripts, and stylesheets.
