The explosion of the Web has strongly impacted all of us. It has become a critical tool for businesses and consumers to exchange information, conduct commerce and more importantly to develop and maintain communication. With Web traffic increasing at an exponential rate, and sites incorporating media-filled contents, it has demanded Internet infrastructures to be compliant with the growth.
             A company's web presence is increasingly seen to be of utmost importance. The introduction of E-commerce has opened up opportunities for businesses. Two main categories streamed from the development: business-to-business; and business-to-consumers. With applications designed for those two specific purposes, web performance is now believed to be a critical matter. Its efficiency can strongly correlate with the growth of sales and revenues. On the other hand, slow and unresponsive web sites have failed to make their ways into the competition.
             Today's Internet architecture is based on the concept of centralized servers distributing files and information to various points on the Internet. In this situation, a few basic causes of slow Web environments are derived:
             · Network link congestion – The backbone of an Internet Service Provider (ISP) is the link that it has to the Internet. A considerably small link would strongly influence the speed of its Internet operations.
             · Network equipment congestion – Equipments used to control networks e.g. network interface cards (NIC), hubs and switches, and routers have a great impact on the speed of the overall performance of a network.
             · Web server congestion – The success of a web site strongly correlates to a high number of user requests. This situation can give rise to congestion if the web server processing management is inadequate.
             · Distance delay – The delay of files and information being sent and received over long distances can al...
