Classic architecture of a Web-based informational system (WBIS) consists of HTML browser on the client side and Web and database servers on the server side. Information is concentrated and updated in a database and a user of WBIS receives it upon a request. Depending upon WBIS aim different demands are made to its components. For high-speed communications systems it's important not only communication channels throughput but performance of communication nodes and of software components selected for the system construction. For real-time WBIS that monitors industrial, environmental, or man-caused relatively fast process it's typical permanent data flow from the number of data sources. A system must process, visualize and selectively save data. This kind of WBIS' dzfferfrom e-commerce WBIS' in demands for type of data, data amount per time unit and type and time of data processing and visualization. That is why ecommerce oriented benchmarks like TPC-W can't simulate behavior of monitoring WBIS. As a result a benchmark for Win32 software components of monitoring WBIS that simulates different modes of its work was developed. The components are Java-applets, CGI scripts, COMIDCOM objects, Microsoft IIS-4 and SQL 7.0 servers. The demands for Engineering level of the Novosibirsk Hydroelectric Power Station automated system of maintenance and control were used as basics. In the benchmark a system must monitor 1 000 of 1 6-bit parameters with data renewal of 1hz. The results obtained let optimize classic architecture of WBIS and methods of its software components interaction for achieving better system performance in monitoring tasks.
