TAILIEUCHUNG - Flash: An Efficient and Portable Web Server

In this paper, we present REED, a system for Robust and Efficient Event Detection in sensor networks that addresses this limitation, enabling the deployment of sensor networks for the types of applications described above. REED is based on TinyDB, but extends it with the ability to support joins between sensor data and static tables built outside the sensor network. This allows users to express queries that include complex time and location varying predicates over any number of conditions using join predicates over these different attributes. The key idea behind REED is to store filter. | USENIX THE ADVANCED COMPUTING SYSTEMS ASSOCIATION The following paper was originally published in the Proceedings of the 1999 USENIX Annual Technical Conference Monterey California USA June 6-11 1999 Flash An Efficient and Portable Web Server Vivek S.

Pai Peter Druschel Willy Zwaenepoel Department of Electrical and Computer Engineering Department of Computer Science Rice University Abstract This paper presents the design of a new Web server architecture called the asymmetric multi-process event-driven AMPED architecture and evaluates the performance of an implementation of this architecture the Flash Web server. The Flash Web server combines the high performance of single-process event-driven servers on cached workloads with the performance of multiprocess and multi-threaded servers on disk-bound workloads. Furthermore the Flash Web server is easily portable since it achieves these results using facilities available in all modern operating systems. The performance of different Web server architectures is evaluated in the context of a single implementation in order to quantify the impact of a server s concurrency architecture on its performance. Furthermore the performance of Flash is compared with two widely-used Web servers Apache and Zeus. Results indicate that Flash can match or exceed the performance of existing Web servers by up to 50 across a wide range of real workloads. We also .
