Actual and perceived response time, user interface, and security via usage patterns

摘要

A variety of performance optimization techniques are provided that are based upon a history of a user's usage patterns. To reduce actual response time, the system prefetches information in anticipation of the user's request. To reduce perceived response time, if a response to the user's request is likely to be delayed, the system initiates other anticipated fast-response processes for the user. To ease the user's interaction with the system, the user's interface is dynamically modified to facilitate the entry of anticipated requests. To improve security, increased security measures are invoked when the user's request pattern is inconsistent with prior request patterns. At a system level, performance assessments and optimizations, including dynamic load balancing, are based on the prior usage patterns of mulitple users.
