Thesis (MTech. degree in Information Networks)--Tshwane University of Technology, 2007. === The purpose of this study is to determine how long South African users are willing to wait before they become frustrated with a website(s) and or webpage(s) and take their business elsewhere. Furthermore it determines what the consequences of wait on users are. A sample of twenty South African participants were required to complete four different web tasks (the tasks were all related to finding a website, navigating a round a website, registering a user on a website, finding and transacting products to purchase) at one of four different download delays (two second, five second, eight second, and ten second delays). Usability measures of effectiveness, efficiency, and satisfaction were used to evaluate the point at which participants believed the delay was negatively affecting their interaction with the website. This research found that a two second delay was acceptable to participants across all four tasks. A five second delay was acceptable on some tasks. The eight second delay was, in most tasks, the most disrupting on user performance (more so than a ten second delay).
