In essence, the World Wide Web is a worldwide string of computer databases using a common information retrieval architecture. With the increasing popularity of the World Wide Web, more and more functions have been added to retrieve not only documents written in HTML (Hypertext Markup Language), but also those in other forms through the Common Gateway Interface (CGI), by constructing HTML documents dynamically. Dynamic construction of HTML documents for handling information such as digital libraries is slow and requires much more computer power. A significant performance bottleneck is the initialization and setup phase for a CGI process to gain access to the system containing the data. In this paper we describe the design and implementation of a Connection Manager Interface on IBM SP systems. The Connection Manager provides cliette processes to serve CGI requests and eliminates such bottlenecks. An IBM SP system is used for this emerging area to show that our design and implementation is flexible enough to take advantage of the High-Performance Switch in an IBM SP system. We trace and monitor this scalable Web services using UTE (Unified Trace Environment) tools, and present its performance analysis and visualization.
