In this paper, we present an in-depth analysis of the memory system performance of the DSS commercial workloads on two state-of-the-art multiprocessors: the SGI Origin 2000 and the HP V-Class. Our results show that a single query process takes almost the same amount of cycles in both machines. However; when multiple query processes run simultaneously on the system, the execution time tends to increase more in SGI Origin 2000 than in HP V-Class due to the more expensive communication overhead in SGI Origin 2000. We also show how the rate at which the number of data cache misses, context switches and the overall execution time increases when more query processes run simultaneously.
