This report consists of a series of simulation studies of the hardware throughput of a specialized machine known as the database computer DBC. Although raw hardware performance of the DBC can be estimated in an order of 80 to 160 times that of conventional software-oriented database management systems, there is the need of knowning the DBCs response time to user access requests, load condition to various request types, and potential bottlenecks which may be caused by uneven performance matching of the key DBC components. The simulation studies are intended to address the need. The simulation programs are written in GPSS and run on an IBM 370168. All of these results are plotted in graph form. Prediction of the results, interpretation of the graphs, and observation of the deviations are the main effort of the simulation studies. Very good conclusions are obtained concerning the DBCs response time, load condition, and throughput bottleneck. Author
