A Performance Model of Speculative Prefetching in Distributed Information Systems
Previous studies in speculative prefetching focus on building and evaluating access models for the purpose of access prediction. This paper investigates a complementary area which has been largely ignored, that of performance modelling. We use improvement in access time as the performance metric, for which we derive a formula in terms of resource parameters (time available and time required for...
متن کاملResource-aware Speculative Prefetching in Wireless Networks
Mobile users connected to wireless networks expect performance comparable to those on wired networks for interactive multimedia applications. Satisfying Quality of Service (QoS) requirements for such applications in wireless networks is a challenging problem due to limitations of low bandwidth, high error rate and frequent disconnections of wireless channels. In addition, wireless networks suff...
متن کاملEffect of Speculative Prefetching on Network Load in Distributed Systems
Previous studies in speculative prefetching focus on building and evaluating access models for the purpose of access prediction. This paper, on the other hand, investigates the performance of speculative prefetching. When prefetching is performed speculatively, there is bound to be an increase in the network load. Furthermore, the prefetched items must compete for space with existing cache occu...
متن کاملSpeculative prefetching of optional locks in distributed systems
We present a family of methods for speeding up distributed locks by exploiting the uneven distribution of both temporal and spatial locality of access behaviour of many applications. In the worst case, some of our methods will not produce higher network latencies than equivalent conventional distributed locking methods. In best case, the total number of messages can be constantly bounded, appro...
متن کاملWeb Server Performance Optimization using Prediction Prefetching Engine
The long-term success of the World Wide Web depends on fast response time. People use the Web to access information from remote sites, but do not like to wait long for their results. The rapid growth in the amount of information and the number of users has lead to difficulty in providing effective response time for the web users and this increased web latency; resulting in decreased web perform...
