Some results from a new technique for response time estimation in parallel DBMS

The need for tools for performance prediction of parallel database systems is generally recognised. One such tool which has been developed (Steady) is based on analytical techniques to obtain a rapid estimate of performance. The approach to predicting response time involves a heuristic approximation coupled with standard queueing solutions. This paper reports on preliminary results for both maximum transaction throughput and response time obtained in comparing this approach against actual measurements.
