The Internet and World Wide Web (WWW) have made electronic commerce a reality. According to an estimate the WWW presently contains more than 800 millions pages, encompassing about 6 terabytes of text data on about 3 million servers. As the number of web users is increasing rapidly, there is a need to build fast and efficient systems for handling users requests on the web. Jakob Nielsen's figures from his keynote talk at the QualityWeek 1999 Conference & Exhibition suggest that the webpage should be received within 7 seconds after the request from the user. The real answer to "Too slow" probably is more subjective, but at the same time probably not too terribly different.
