Workload Analysis of SPECjEnterprise2010

In this paper, we present a case study of measuring the performance of SPECjEnterprise2010 and its workload analysis on two different configurations, where either the application or database server is the performance bottleneck. The CPU utilization of the application and database servers behave differently for the increasing system size. They draw square-root and quadruple like functions, respectively. By measuring each transaction type separately, we find that the source of these non-linear factors is the Browse transaction. Also, the sum of the CPU utilization of each transaction type executed individually overestimates the total CPU utilization when all transaction types are executed simultaneously. In the performance modeling methodology of SPECjAppServer2004 found in the literature, the CPU time for each transaction is assumed to be constant and it is obtained by the measurement of individual execution. However, from our observations, this methodology cannot be directly applied to SPECjEnterprise2010.
