Abstract
A fundamental trend for servers in network-centric computing environments is to evolve from traditional database and transaction servers to information distribution and handling systems. In addition to documents written in the HyperText Markup Language (HTML), data stored in other forms can be retrieved through the Common Gateway Interface (CGI). A significant performance bottleneck is the initialization and setup phase for a CGI process to gain access to a backend server. In this paper, we describe the design and implementation of a distributed Web server for CGI processes to acquire services efficiently. A Connection Manager Daemon (CMD) is developed to provide a number of clients, which are connected to backend servers to eliminate initialization costs for incoming requests. A Cache Manager is implemented to speedup response time in case of repeated requests. We also trace and monitor the Connection Manager Daemon as well as its clients using extended UTE (Unified Trace Environment) tools, and present its performance analysis and visualization. The platforms where we conduct this study include a single-node workstation, a cluster of workstations, and an IBM Scalable Parallel (SP) system.
