Methods, apparatuses, systems, and articles of the invention are used to enhance the efficiency of a computing environment, and to improve its responsiveness to one or more users. In the invention, queuing of data or computer instructions is avoided since this would detract from best case performance for a network environment. The rate-limiting factor for the network is determined, and all constraints imposed by the rate-limiting factor are determined. Business logic is programmed in modules sufficiently small to avoid queuing of instructions. Data is stored by frequency of access and persistence to increase responsiveness to user requests. Requests for data from a data storage device are fulfilled not only with the requested data, but also additional data which is likely to be requested in the navigational hierarchy of presentations to which the requested data belongs.
