Although Web prefetching is regarded as an effective method to improve client access performance, the associated overhead prevents it from being widely deployed. Specifically, a major weakness in existing Web servers is that prefetching activities are scheduled independently of dynamically changing server workloads. Without proper control and coordination between the two kinds of activities, pr...

Even with rapid advances in the technology of processors, memory, storage and networks, the growth in web-based information and the increased use of web-based applications continue to place demands on the Internet. Performance of web servers continues to present challenges. Delays in access to web-based information, i.e., access latency, continues to be a serious problem, even with higher bandw...

II Declaration I declare that the work described in this dissertation is, except where otherwise stated, entirely my own work and has not been submitted as an exercise for a degree at this or any other university. Abstract The exponential growth of the Internet and the increasing demands put upon Web servers has created the need for a scalable clustered Web servers. In this paper we attempt to ...

High-performance Web servers are essential to meet the growing demands of the Internet and large-scale intranets. Satisfying these demands requires a thorough understanding of key factors affecting Web server performance. This paper presents empirical analysis illustrating how dynamic and static adaptivity can enhance Web server performance. Two research contributions support this conclusion. F...

Many research efforts have been directed towards avoiding or dissolving the network congestion,which is caused by an increase in network traffic. However, there has been little recent discussion on improvement of the performance of Internet endhosts in spite of the projection that the bottleneck is now being shifted from the network to Internet endhosts. In this thesis, we present a novel schem...

Web servers are ubiquitous, remotely accessible, and often misconfigured. In addition, custom web-based applications may introduce vulnerabilities that are overlooked even by the most security-conscious server administrators. Consequently, web servers are a popular target for hackers. To mitigate the security exposure associated with web servers, intrusion detection systems are deployed to anal...

This paper provides two contributions to the study of highperformance Web servers. First, it outlines the optimizations necessary to build efficient and scalable Web servers and illustrates how we’ve applied some of these optimizations to create JAWS. JAWS is a high-performance Web server that is explicitly designed to alleviate overheads incurred by existing Web servers on high-speed networks....
